can you please share some knowledge about Quantum Numbers?(My teacher is kinda bad at teaching, neither me or my classmates get it) tHANKS!

Of course, I’m happy to share my knowledge about quantum numbers! 

Let’s start off with the question: what exactly are they?

Quantum Numbers: list of numbers that characterize an outer electron in an atom. Or in simpler words, the location of an electron within an atom! These numbers are represented in the form: .

There are four electronic quantum numbers that make up the “location”

Principle Quantum Number (n): refers to the electron shell or I like to call the energy level. This can be determined by the row that the atom is located in. For example, sodium is located in the third row so it’s principle quantum number will be n = 3.Note: n cannot equal 0 because there is no such thing as a zero energy level.

Orbital Angular Momentum Quantum Number (l): refers to the shape of the orbital (or subshell). In which, there are four* types of subshells - s, p, d, and f. Each of these subshells can be assigned a number where s = 0, p = 1, d = 2, and f = 3. To calculate the possible values for this quantum number take the formula: n-1. For example, fluorine is in the second row on the periodic table. So n = 2 and it’s possible l values are 1 and 0 because fluorine contains S and P orbitals. *In theory, there are infinite types of subshells but we only know of the four types that can be assigned to current atoms. (Correct me if I’m wrong!)  Tip: split up the periodic table in the types of subshells they represent. This will give you a better understanding of what l value to assign to a specific electron when you’re determining it’s “location”.

Magnetic Quantum Number (ml): refers to the number of orbitals and the orientation. In other words, where in the subshell is the electron located. To find this value take the formula: -l…0…+l. Going back to the fluorine example, let’s say the electron has an l = 1 so it’s ml = -1, 0, +1. Which makes sense because l = 1 indicates an P orbital and there are three orbitals in the x, y, z positions. So the electron can be located in either three of these S orbitals.

Electron Spin Quantum Number (ms): refers to the spin of the electron. This number is simple, the electron either spins +½ or -½ though I’m not positive if the negative or positive value goes first when assigning them.

House Address Analogy

Let me tell you a good analogy I heard from my professor when I took general chemistry. Think about quantum numbers like an address of someone’s house. Where n = country, l = state, ml = street, and ms = building number. Each number tells you how precise they are with the location of the house. So convert that into the address of an electron! 

Further Example: Find the quantum number of the 1st outer electron in a lithium atom. 

So lithium is located in the second row of the periodic table, n = 2. The electron we are focused on is in the first row, l = 0 because it’s the section for S orbitals (refer to the first diagram I posted about splitting sections of the periodic table into their orbital types). Now the ml value can only be 0 since an S orbital is only made up of a single sphere. Lastly, the ms value is where I get a little confused, so I’m going to go off the idea that -½ comes first. And there we have it! The quantum numbers for the 1st outer electron in a lithium atom: <2, 0, 0, -½>.

In case my explanation wasn’t fully comprehensible… I’m going to list some extra help and practice problems below.

Quantum Numbers

What Are Quantum Numbers?

Quantum numbers are values that explain the movement of electrons within an atom. These numbers, as their name suggest, are heavily influenced by quantum mechanics, a branch of physics that deals with the movement and behavior of subatomic particles. There are four of these numbers – the principal quantum number, the angular momentum quantum number (also known as the orbital quantum number), the magnetic quantum number, and the electron spin quantum number. Each of these quantum numbers cover a quantum mechanical principle, and, together, forms the basis of the branch.

These quantum numbers also define electron configurations – an important concept in chemistry. These configurations define how an electron is distributed within an atom. In terms of quantum numbers, the electron configuration represents the amount of electrons that can fill an element. The most stable elements – the noble gases – have the maximum amount of electrons allowed by their quantum numbers.

Both the electron configuration and the quantum numbers of elements are determined by the energy that electrons have. The electrons with the lowest energy which are closest to the nucleus are referred to as core electrons while those with the highest energy are labeled valence electrons and are used to increase atomic stability through chemical bonding.

Principal Quantum Number

The Principal Quantum Number, represented by the letter n, is used to define the energy level of the electron in any atom. In chemistry, the electron’s energy level is also referred to as the energy shell. As previously stated, the core electron shell is that with the lowest energy and, therefore, would have a lower principal number. Since atoms have a tendency to fill their lowest energy shells first, the lowest principal numbers are where we start.

The electron shells are labeled in two ways – alphabetically from the letter K to O or numerically from the letter 1 to 5. These are equivalent; K is the same as 1 and O is the same as 5. Typically, this quantum number is represented numerically instead of alphabetically. Although there is the chance that higher principal quantum numbers may be used, n = 1 to n = 5 are the most common range.

Angular Momentum Quantum Number

The Angular Momentum Quantum Number, represented by the letter l, is also called the Orbital Quantum Number because it determines the path or area that the electron travels within, which we define as an orbital in chemistry. Orbitals are governed by an electron’s angular momentum, which is the physical product of an electron’s moment of inertia and its angular velocity. In spite of this, it is important to note that calculating the angular momentum of an electron cannot be done conventionally because the electron exhibits wave-particle duality, which is the nature of a particle to behave like both a waveform and a particle. As such, the angular momentum in a quantum mechanical sense is often referred to as the quantized angular momentum.

Regardless, the angular momentum quantum number, l, is also represented both numerically – commonly by an integer value from 0 to 3 – or alphabetically – with the letters s, p, d and f, respectively. Unlike the principal number’s convention, this quantum number is typically referenced with its letters. As with the principal quantum number, the value of l can be greater than the commonly used range, however the elements that correspond to greater l values have not yet been discovered. Moreover, the orbital quantum number is limited by the principal quantum number in that l must always be one less than n. In other words, the orbital quantum number can only go up to n – 1. This means that if there is a principal quantum number of 2, the orbital quantum number is equal to 1. The result of that is that the highest orbital in the element is a p orbital. That, however, does not mean that all electrons are within the p orbital. Remember, electrons prefer to fill the lowest energy shells before moving to the next one, meaning an l of 1 means that there are electrons both in the s and p orbitals. It is because of this that when a principal quantum number is given, the value of l given is usually the range of possible values; n = 2 corresponds to l = 0, 1.

While the principal quantum number tells you how many electrons are contained within the atom, the orbital quantum number will tell you how they are organized within each electron shell. Therefore, this quantum number defines the electron “subshell”. Every electron within the same subshell contains the exact same level of energy, and, just like with electron shells, the higher subshells contain more energy than lower subshells.

Magnetic Quantum Number

With an increase in the number of electrons comes an increase in the amount of orbitals and how they must be oriented to maintain the lowest possible energy within an atom. The magnetic quantum number, represented by the letter m, provides a value to this orientation. Keep in mind, however, that since this depends upon the number of subshells, it is limited by the angular momentum quantum number. That said, m is equal to the range of -l to l. So, for example, if there are two subshells, represented by l = 1, the value of m is 3 (-1, 0, and 1).  This means that there are 3 orbital orientations in the highest subshell. In order to find the total value of m, however, you must remember that an l of 1 includes l = 0. In that case, m is equal to 1, making the total amount of orientations in this element 4.

Spin Quantum Number

The spin quantum number, or s, is the final quantum number and is also the only quantum number that has no dependence on any of the other quantum numbers, but instead depends on the quantum mechanical properties of electrons themselves. This number determines the number of electrons within any given orbital orientation, as per an important quantum mechanical principle – the Pauli Exclusion Principle. It states that two electrons cannot have the exact same quantum mechanical state. This state is according to a quality that electrons have called “spin” (the electrons do not literally spin, this is just a name) which is either defined as +1/2 or -1/2. In one orbital orientation, according to the Pauli Exclusion Principle, there cannot be two electrons with the same spin. Therefore, the spin quantum number dictates that there is a limit of two electrons, one with one spin and one with the other, in any given orientation. The amount of electrons in any given element is represented with a 1 or 2 in exponent form on the angular quantum number, representing if that element has one or two electrons in that subshell.

What is main energy level or shell?

            An electron main energy level or shell is the set of allowed states, which share the same principal quantum number, n (the number before the letter in the orbital label), that electrons may occupy. An atom's nth electron shell can accommodate 2n2 electrons, e.g. the first shell can accommodate 2 electrons, the second shell 8 electrons, and the third shell 18 electrons. The factor of two arises because the allowed states are doubled due to electron spin—each atomic orbital admits up to two otherwise identical electrons with opposite spin, one with a spin +1/2 (usually noted by an up-arrow) and one with a spin −1/2 (with a down-arrow).What is main energy level or shell?             An electron main energy level or shell is the set of allowed states, which share the same principal quantum number, n (the number before the letter in the orbital label), that electrons may occupy.

What is the sublevel and orbitals?

            A sublevel or subshell is the set of states defined by a common azimuthal quantum number, ℓ, within a shell. The values ℓ = 0, 1, 2, 3 correspond to the s, p, d, and f labels, respectively. The maximum number of electrons that can be placed in a subshell is given by 2(2ℓ + 1). This gives two electrons in an s subshell, six electrons in a p subshell, ten electrons in a d subshell and fourteen electrons in an f subshell. The numbers of electrons that can occupy each shell and each subshell arises from the equations of quantum mechanics, in particular the Pauli Exclusion Principle, which states that no two electrons in the same atom can have the same values of the four quantum numbers.

            When an electron is in a particular energy level, it is more likely to be found in some parts of that level than in others. These parts are called orbitals. Orbitals of equivalent energy are grouped in sublevels. Each orbital can contain a maximum of two electrons. When in a magnetic field, the two electrons in a particular orbital differ very slightly in energy because of a property called electron spin. The theory of electron spin states that the two electrons in a single orbital spin in opposite directions on their axes, causing an energy difference between them. (Like many models, this explanation is an oversimplification, but for the purpose of this course it is a useful description.)

Each principal energy level has one sublevel containing one orbital, an s orbital that can contain a maximum of two electrons. Electrons in this orbital are called s electrons and have the lowest energy of any electrons in that principal energy level. The first principal energy level contains only an s sublevel; therefore, it can hold a maximum of two electrons.

Elemental Flow - The Orbital Primer pt. 2 (5)

This is it! We have finally reached the conclusion of the orbital arc...or at least the second to last lesson. I’m sure it felt like the Frieza Saga, but I believe that I managed to explain the entirety of orbitals in a concise, but accurate way. Of course, I’ll leave it to you to tell me how I can improve to make this a better story for you. Because, like electrons, we all have to work together here.

In any event, let’s march on and be done with these orbitals. Ah…I can already hear the cheers from the Chemistry 101 students reading this.

Be sure to check out Part 4 for this one. You can’t understand where this one begins without seeing where the other one ends (hence ‘pt. 2’).

Now, it is time to explain the last quantum number.

Spin Quantum Number (s)

Electrons are trying to get rid of their energy in any way possible. Orienting themselves in a way that lowers energy is a good starting point, but they still have plenty of internal energy. In fact, electrons have their own, internal angular momentum, separate from the orbital angular momentum (l).

This was determined after a 1922 experiment by German physicists Otto Stern and Walther Gerlach. The aptly named Stern-Gerlach Experiment involved firing a beam of silver atoms* through a inhomogenous, or uneven, magnetic dipole and observing the results on a detecting wall at the end. The result, surprisingly, was that the beam was deflected in only two directions, landing flush against the wall in two bands.

But how could that be? There’s no way that there should be two, specific places in which the atoms ended up.  

If you think about it, if you threw twenty bar magnets past two huge magnets and looked at where they ended up, they would all be stuck on the wall in random places. After all, you have no idea what direction those magnets were when you threw them or how much attraction or repulsion one magnet had than another one, so you should have no idea exactly how they will come out. Shouldn’t it have been the same for these atoms?

In order to explain the significance of this inconsistency, I’ll need to diverge for a second into the physical quantity of momentum.

Gaining Momentum

Given that we know, from classical linear momentum calculation that there must a velocity, some speed over some time from some position which is usually produced by some force (say that ten times fast), and a mass, or the amount of matter an object has. This tells you how much, in numerical form, an object moves. In fact, you likely already knew the definition of “momentum” without knowing how to put it in words. Classical angular momentum is almost completely the same. The only difference is that an axis is involved, around which your mass rotates.

Thus, the two relative quantities are the moment of inertia and angular velocity. The latter is simply the rate at which rotation occurs. On the other hand, the moment of inertia, also known as the angular mass, is used to depict how much torque, or rotational force, you need to move an object a certain distance around an axis with respect to a certain position. The classic example of this is the tightrope walker.

If it was super easy to cause the one walking on a tightrope to flip around the rope (if gravity didn’t exist), then you would say that their moment of inertia is low. But when one walks across a rope you usually see them stick their arms out or hold a long rod. That single act increases the moment of inertia because you have changed the center of the mass, where the force acts. That is, more rotational force would be needed to rotate the walker. Now, Matthew, why did you go through the effort of explaining momentum here? Patience, viewer! The science will wrap together in a nice ribbon. Just in time for Christmas.

Magnets Start Small

I mentioned, from the now legendary Part 2, that electrons, as charged particles, can generate a magnetic field just by moving. It so happens that we know that electrons are “orbiting” the nucleus, and therefore, they must be exhibiting some sort of magnetic field as it is repeatedly revolving in this closed loop. But we never talked about what that field is doing. It wouldn’t make sense for the magnetic field to just disregard the electron and there is definitely no reason for the electron to not feel the force of the magnetic field.

Image via SchoolPhysics

By the way, if you orient your right-hand’s four fingers so that they are going along the path of the electron and then point out your thumb, that gives you the direction of the magnetic field. Every time. It’s called the Right-Hand Rule.

What would happen if you were to hold your hand on a ball lying on a table and then push your hand forward? The ball would roll in the direction your hand moves. It’s the same with electrons – they experience a rotational force, torque, from the magnetic field. The rotating electron creates another effect, according to electrodynamics. It now becomes a natural magnetic dipole, which is an object that generate magnetic fields that experience torque in such magnetic fields due to the presence of two opposite poles. In many ways, their magnetic effects are just tiny bar magnets. Electrons, too, have a “north” and “south” pole, or, more specifically, two poles at which their magnetic fields are strongest.

Image via Live Science

This is a dipole. You’ve seen bar magnets before.

 So, let’s do a roundup of what we just learned.

 Electrons generate magnetic fields which creates torque on them causing them to rotate and become similar to bar magnets. You should already recognize, then, where the concept of an electron’s angular momentum comes from. Indeed, electrons exhibit their own magnetic moment, from the rotational force, and, coupled with their motion, must create angular momentum!

 This is the origin of the theoretical “spin” that electrons have. Although we, realistically, don’t know if the electrons are spinning or not, this is just a name we give conventionally. You will learn why our convention fails us, especially when it comes to quantum mechanics, later.

 But, I digress. With all of that said…how did the electrons only end up in two places in the Stern-Gerlach Experiment?

 A Discrete Solution

 Stern and Gerlach were smart men. They knew, from Bohr’s prior experimentation of the electron, that it must be quantized. So when they crafted this experiment, they expected a quantized result. That is exactly what they saw. But just because they were correct in their hypothesis doesn’t mean their foundation was solid – a lesson for all of you upcoming scientists.

Image by Bill Watterson

Although that’s a result that you could hypothesize based on an expectation gained after seeing the ice in a glass of water melt, the foundation is all wrong.

The quantum mechanical theory of the time wasn’t correct. Their conclusion that the result was due to the quantization of the electron was not the reason for the quantized result.

 It was because of the electron’s angular momentum was directed in two specific direction. We call these half-spins, since one beam was split evenly into two. Basically, the momentum on the electrons directed the beam either upward or downward according to the direction of their rotational moment.

 A side-note: all elementary particles that hold these spins equal to ½ are called fermions, whereas if their spin value was 1 (what the value would be if the one beam went straight through without any division), it would be called a boson, a word you’ve likely heard before if you’re into physics. These are the two categories in which all particles in the universe reside.

 A Return To Form

 So...how about another summary?

 The Principle Quantum Number (n) determines the energy level, and thus, the electron’s shell. It is conventionally shown with a number from 1 to 5. The Orbital Quantum Number (l) determines where the electrons are with respect to the nucleus. It shows the sub-shell and is typically denoted with a letter (s, p, d or f) according to its number (0, 1, 2 and 3). The Magnetic Quantum Number (m) tells how many subshells there are. It is determined by looking at the subshell and taking the range from -l to l. Lastly, the complex Spin Quantum Number (s) determines whether the electron’s “spin” is +1/2 or -1/2.

 Lastly, there’s the Pauli Exclusion Principle, watching over these Quantum Numbers to make sure they behave themselves. No two electrons can have the same quantum mechanical state within the same atom. It was the aforementioned spin quantum number that proved this; remember that the electrons in the Stern-Gerlach did not simply mix – there was a distinction between +1/2 and -1/2. Furthermore, given that the Principle only works with differing quantum mechanical states, only fermions follow this Principle.

Image via futurespaceprogram

 This opens up a very important piece of orbital theory.

 That spin quantum number shows a great deal, indeed, folks. Because that Pauli Exclusion Principle makes it so that each subshell can only have two electrons – one with the positive spin and one with the negative spin.

 And that, my friends, will guide you into the Aufbau Principle…which we will discuss next time.

 The next lesson will end the Orbital Arc...I hope you’re ready. Because afterward, things will really pick up.

 Please ask questions if you are lost somewhere in these five parts. And share amongst all of your friends – not just the ones interested in science. We can all learn. We just need to light the fire.

*If you understood everything up to this point, you might be able to reason why silver atoms were used. I want to ask you why and give you these three hints to help you: 1) Use the periodic table 2) Orbital Quantum Number 3) Electrons and Protons

Elemental Flow - The Orbital Primer pt. 1 (4)

Image by Randall Munroe via xkcd

|| by matthew

This comic gave me a good laugh, despite not being directly related to quantum mechanical orbitals...

In any event, we are back again! I know how much you were looking forward (or perhaps dreading) this part. Well, if not looking forward to, perhaps still trying to reason how all of this is going on within every element in your body and facing a slight existential crisis. All I have to say, in that case, is to try not to worry about it, and, of course, prepare for another dive into the boundary of quantum mechanics and chemistry.

I, again, recommend that you check out the previous parts of the Elemental Flow series, especially Part 2. Familiarizing yourself with the quantum mechanics of electrons before this lesson will make this a smooth experience.

Quantum Numbers

What do the letters “s”, “p”, “d”, “f”, Aufbau, spin, and shapes have in common?

You might be scratching your head and wondering, “Why is he asking me this when I know he’s going to tell me.” And you’re right.  Let’s break out our handy dandy…periodic table. And notebook, if you have one (I got you, 90s kids).

Image via Science Notes

Orbitals are organized according to their energy levels. Naturally, every element on the periodic table must exist at a separate energy state in nature than each other (otherwise, what you learned in Part 1 and Part 2 would be meaningless – electrons have no need to configure themselves in different ways if every atom exists at the same energy level). Therefore, there must be a different orbital for each element. And, indeed, there is. The periodic table shows that, at the bottom of each element, there is a different electron configuration for each element. This exclusivity in configuration is called the Pauli Exclusion Principle.

Attentive readers might have already noticed the letters at the bottom of the elements on the periodic table – “s”, “p”, “d”, and “f”.

These labels are only descriptors of one of four quantum numbers. 

If you are lamenting the word “quantum” after Part 2 of the Elemental Flow series, don’t fret. A quantum number is a quantity within a quantum mechanical system. Since electrons are quantum mechanical systems, they hold specific quantities. That’s all.

Electrons have four such quantities. We call them the principal quantum number, or n, the orbital quantum number, or l, the magnetic quantum number, or m, and the spin quantum number, or s.

The Quantum Dive – Breaking the Shells

1) Principal Quantum Number (n)

The first, n, is the number that labels the energy level of an electron. Since we know, from Part 1, that the electrons with the lowest energy are the ones closest to the nucleus, we can tell that the lower the value of n, the lower the energy level. In chemistry, the energy level of an electron is described as its electron shell.

These shells are labeled from K to O starting from their innermost shell to their outermost shell, according to their principal quantum number. To be clear, an n of 1 is referred to as the K shell, n = 2 is L, n = 3 is M, n = 4 is N and n = 5 is O. While they do have this alphabetical label, when describing shells, more people recognize the numeric value of n. However, they can help you organize when we talk about the subsequent quantum numbers.

2) Orbital Quantum Number (l)

Next up, l. This quantum number tells about the orbital’s angular momentum, or the momentum brought about by rotation of electrons around some center – the nucleus.

Before I move on from here, I did want to explain this number more carefully.

For those familiar with astronomy, this quantum number is also called the azimuthal quantum number, as an azimuth is a certain angular measurement within a sphere.

Image via UOregon

Within our three-dimensional world, we can describe the position of anything in relation to anything else. As you can see, the azimuth and altitude give the direction of a star in this spherical system. North is usually used as the starting point for an angular calculation when comparing the horizontal position of a star and the altitude is given as angle from the observer in the center to the position on the sphere that the star is located.

But how does this relate to an electron? Take a look at this:

Image by tonfilm via vvvv

The observer is the nucleus, or, in this image, where the x, y, and z axes (representing each of our three dimensions) connect. The star is the point P, or the electron, with some x, y, and z coordinate. The angle between north, or the x-axis, and the point is defined as the azimuth. Lastly, the altitude angle would be the angle between the z-axis and the position of the point.

If the electron was just a point, or particle, then this would be a simple case of calculating the ordinary angular momentum.

But it isn’t just a particle, is it?

The wave nature of electrons.

The angular momentum is harder to calculate in this system than it is in ordinary physics, due to the Wave-Particle Duality of the electron (discussed in Part 2). The electron is traveling quickly on a wave-like pattern. At any given time, we are unsure of where the electron may be. Instead of treating the electron like a particle, it is treated like a standing wave. More simply put, its wave functionality, constant and uninterrupted as it is, is used to determine its angular momentum. Therefore, the orbital angular momentum, is calculated completely differently than the classical angular momentum, which will be discussed when we reach the spin quantum number.

Perhaps the actual mathematics can be shown in a separate lesson if the interest is great enough? For now, recognize that, by solving this equation for the angular momentum, you receive non-negative integer values, or 0, 1, 2, 3, etc.

Aha! A new possibility reveals itself. If you were to believe that electrons were like their classical systems, you would probably say that it’s impossible for an object that’s moving to have 0 momentum. After all, if you’re walking down the street, you have momentum; how could an electron which is constantly revolving around the nucleus have 0 momentum? But quantum mechanically, a system with 0 angular momentum or, in other words, l = 0, simply orbits the nucleus in its wave-like pattern along the xy plane without any z altitude. The electron only has an azimuth, no altitude.

When I said in the last part that you had already learned about orbitals, this is what I meant. Because an electron orbiting the nucleus on an xy plane looks oddly familiar…

The Bohr Model of Hydrogen

Is that...? Why, yes it is! The Bohr Model! He did come up with the initial idea of orbitals. was that dastardly scientist was right!?

Not so fast.

First, let’s clean up this image. Since we’re not concerned with the electron’s decrease in energy state (like we were in part 2 when this was being explained), let’s look at the hydrogen atom at its lowest energy state.

Image via Chemistry LibreTexts

The electron is still on the n = 1 orbital and orbiting the nucleus like above. Only the n = 2 and n = 3 orbitals have been removed.

Bohr was only correct when it comes to things with one electron and an angular momentum of 0. This is because Bohr’s elementary model only observes the energy between the nucleus and the electrons only, not the energy created between the repulsion of electrons. The image above shows the only case in which the Bohr model is correct - with the hydrogen atom. Hydrogen only has one electron and its nucleus, meaning this fits Bohr’s model. Furthermore, as per the aforementioned Pauli Exclusion Principle, there are no other elements like hydrogen in nature.

To wrap up the second and most complicated quantum number, we make note of the fact that we can’t really know what the xy-axis is as it electrons see it.

To conceptualize what I’m saying, think of the image above as the wheels on a gyroscope.

Of course, in a quantum mechanical system, there is more discrete and fast motion, but this is a fantastic example. Now, if the revolving electron in the Bohr model was taking any of the wheels in the above gyroscope, you can understand why it would be hard to tell exactly where the electron would be, let alone where its x and y axes are.

But what you do know is that the electron is somewhere within the sphere made by the rotating gyroscope wheels.

This might sound familiar to you who remember or re-read Part 2 because this is the exact conclusion you derive from the Electron Cloud model that  Schrodinger developed!

I love it when science comes together...You gotta admit, that’s pretty cool.

With all of that said, the purpose of the orbital quantum number is to tell you the shape of the electron subshell. Like the principal quantum number, these have an alphabetical naming system too…and it’s one you’ve already seen! That is: s, p, d and f. l = 0 to l = 3 represents s to f. Unlike the principal quantum number, however, it is conventional to use s, p, d and f rather than the numeric orbital quantum number value.

With that said, if the principal quantum number, n, is equal to 1 and the orbital quantum number, l, is equal to 0, you have a 1s system, which is the electron configuration of the hydrogen atom (check the bottom of the hydrogen element on your periodic table).

Now, I think after all of that, it’s good to keep ourselves organized.

To recap, the principal atomic number tells us the electron shell or energy level of the element, and the orbital quantum number tells us the electron subshell. There can be multiple subshells in one shell. And each individual electron configuration is called an orbital.

3) Magnetic Quantum Number (m)

Before we wrap up with this image, there’s something important in it that will help you understand the magnetic quantum number. 

You might have noticed above that there are three different p orbitals in the above image. That is due to the different ways an orbital can orient itself within space as the amount of electrons in the system increases. This is what Bohr did not account for in his model; when more electrons enter the system, in order to keep energy as low as possible, the system must orient itself differently within the three dimensions.

The magnetic quantum number is a handy way of telling us how many ways a subshell can orient itself. I say it’s handy because there’s a simple equation to tell you how.

For every value of l, there is a range of values of m from -l to l, including zero.

So, if our system is a d orbital, which is l = 2, there would be 5 ways the subshells could orient themselves, given by the m values -2, -1, 0, 1 and 2.

That’s all there is to that. See? Not so bad.

Intermission

Okay, okay. Break time. We don’t want to overcook your brains with chemistry and quantum theory. Fortunately, what we are going over is, theoretically, all there is to orbitals (without the droll mathematics, of course). And, as you already know, this leads to some amazing science. After all, after learning about electron shells, the next step can only be how elements combine to reduce energy even further!

Are you enjoying learning about how these microscopic particles work and seeing how something so complex can create something as simple as a drop of water and/or something as ubiquitous as air?

Let me know. I would love to talk science with you guys.

As always, thank you for joining me, and I will see you again very soon.
