#ATOMIC ORBITALS DEFINITION CHEMISTRY FREE#
If there's any information you didn't understand feel free to message me and I'd be happy to answer any other questions.A wave function (Ψ) A mathematical function that relates the location of an electron at a given point in space to the amplitude of its wave, which corresponds to its energy. That specific electron they're talking about. And that the spin of the electron is in the opposite direction. So you didn't really have to worry about ML or the MS but you know that the MLA was within the range of L because it could be negative 10 or positive one. But as far as this question goes it just wanted to know what was the corresponding atomic orbital designation. In regards to n equals two l equals one mouth to see if you know the rules. Another way you can be asked is true or false questions. Well we already said that l equal to one corresponds to the p orbital. Now going back to the question give the corresponding atomic orbital designations for the electrons with the following quantum numbers. And then from there to three S I was just telling you there's an order to the way electrons fill their orbitals. Once the two electrons have filled one ends it will move to to us from 2S. When electrons are filling up in the atom it's going to start at one s. The one we're missing though is the Aufbau principle which pretty much just tells us that the electron does not fill in a random order. Now we talked about the Heisenberg Uncertainty Principle and hunt rule. You can probably find better pictures of these in your Textbook but for completeness I'll tell you that f can hold 14 electrons. And because there's five orbitals ten electrons an F I couldn't draw out. De I tried to draw out as having five orbitals. And each plane can hold two electrons which means that your p can have a total of six electrons. Would I didn't draw with a different planes of the p orbital. We have our S orbital which can hold two electrons and we have our p orbital. So here I drew out or tried to draw out the orbitals. Let's look at the shape of the orbitals before we come back and look at the question.
Because according to Hund's rule You need to have electrons that are in the opposite spin of each other because if they're spinning in the same direction those repel. So our question is just telling us that the electron has a negative spin which means it's in the opposite direction. So you can have a positive or a negative 1.5. And then S just think about spin S for spin. And as you see the ML and our question is within that range so that's good. What are all the possible ML sub-levels so it would be negative one Zero and positive one. So for example our question says l equals one. Okay so what I mean by that is that L is going to range from your positive and the negative L Or the other way around but basically you want to stay within the range of L the negative to the positive. And if it's equal to three we're talking about F Now what is ML ML is the sub orbitals of L. And we're talking about P at L equals two then we're talking about D. So if you have L equals 0 that's as if it's one. Also something that we should know about l is the number corresponds to the shape of the orbital. And then l one thing that we should know is that L What's it n minus one or less basically L cannot equal n. So the higher the number n the further away from the nucleus l is telling us the shape of the orbital which we'll see in the next page I tried to draw out for you. N is telling us what level we're at how far away from the nucleus. So what These orbitals allow us to do is to kind of just have an idea of where the electron is. M equals 0 and MS equals negative 1.5 So why exactly are we trying to figure this out and what is everything mean well according to Heisenberg's uncertainty principle is impossible to determine the exact location and momentum of an electron at a specific point in time single point in time. Now the question states give the corresponding atomic orbital designations for the electrons with the following quantum numbers. So if you have any questions after this feel free to message me or any other chemistry tutor on check will be happy to help. And just know that it's not everything there's a lot to atomic orbitals. There's some background information I'm going to cover before. The topic I'll be covering today is atomic orbitals. Hi my name is Victoria and I'm a chemistry tutor uncheck.
