 Okay, so let's talk about quantum numbers really quick. Let's talk about giving the quantum numbers of I don't know, but we'll do the sixth electron for oxygen. So oxygen the best way to do quantum numbers is to write the orbital diagram. So when we're filling up one two one two, and then one two three four So everybody's cool with that, right? Oh, quick question. So that's how you do like on like say 2p or blocks later You put one in each then you come back and then you start again. Yeah, definitely You have to say that. Yeah, no, no, because they don't like to be in the So let's just think about this, right? So this here is It's increasing in energy. Okay, so anything in chemistry anything in chemistry happens because it likes to be at the lowest energy state, okay, so anybody So obviously this is lower energy than this this lower energy than this, but The electrons don't like to be paired, right? They'll be paired if they have to be there Okay, but what we're implying here is to say that this p x p y and p z if you want to think about in that way All have equivalent energies. Okay, so if there's one guy in this if you think about like houses You know and there's roommates, right? One guy in this house, you know I'll just go to the next house I have a roommate, you know not have to stand on my head. You know what I'm saying So this one I'll do the same thing this guy's left the next one's like well There's no other room for me, you know, so I guess I have to go into that person Okay, so it's just that what this is saying is all of these are at the same energy So that's how you feel this is a total off-boub principle Anyways, where were we? So and do you guys know the car numbers n L? Well Yeah, so principle Angular right magnetic and spin, okay So we're looking what did we say the sixth one? So one two three four five? Six this one here Everybody okay with that? See how I did that thing So the sixth one well its principle energy level is going to be two right because that's the Period that it's in so The angular one describes what? Or type of orbital it's in okay, so s is zero p is one D is two f is three, okay, so this is going to be a what type of orbital p, so it's a one yeah Okay m sub l this is the integers plus or minus This number and in between okay, so in other words minus one zero plus one is everybody okay with that okay, so X in this case minus one zero plus one minus one zero plus one That's how they feel okay, so which one would this one be? This one here minus one, but the one that we circle sorry zero zero right Sorry, I know my hand was And then Spin honestly, you don't know whether the electron goes up Up or down down or up you know, but it's convention to write them up So what I do and I don't know if miss Sanchez will do this But the way I'll always do this is the first electron that goes in is going to be the plus one Yeah How did I count my electrons one two three Or five six seven eight, right you guys got it Should we do another one one of these other electrons on this one? Let's just do one more So let's do it there let's do it different Adam when we're talking about that let's not confuse it with oxygen Okay, so but we'll do another example in a second, okay Well, it's gonna be three s with one and the next one will be three p with three and four s with one and then Five because there's five orbitals in the 3d. Well, but we can do a whole example on that if you prefer You know, I think it would be better to just complete this one and then do that one next, okay But it's a good question. I'm not trying to blow it off Okay, so let's do let's do a different electron. Let's do I don't know this Okay, so what's one electron is that one two three four the fourth electron, okay? So what's any going to be the principal to? L is going to be what? Zero is it's an s orbital, right? So what is M sub L the magnetic number has to be It has to be zero right has to be zero plus or minus zero. There's nothing in between And was this the first electron or the second one that went in? second one so again a lot of people would say Plus or minus, you know, it doesn't matter, but I like to think of it if it's down Okay, can we tell this video? I think we're pretty good on this stuff, right?
