 So, let's do another one of these molecular orbital diagram problems and find the bond order. This time, let's use molecular orbital diagrams to find the bond order and predict whether H2 2 minus exists. If it exists, write the electron configuration, but H2 2 minus is what we're looking at. So, what do we got? We've got H minus and H minus, right? Because that's H2 and 2 minuses. So, when we fill these guys up, we're going to have two electrons because hydrogen normally has one valence electron, we add an electron to it, it's got two valence electrons. And now we put them into our bonding and anti-bonding orbital. So what we're really asking, does this molecule exist or not? Don't go up like that, like that. So in order to figure out if it exists or not, how do we do that? Figure out the bond order. So the bond order, one half times the number of bonding electrons minus the number of anti-bonding electrons. Okay, so the number of bonding electrons is two. Anti-bonding electrons is two. One half, two minus two is zero. So the bond order equals zero. So this does not exist, right? So everybody okay with that? So it also asked us to, well, if it exists, write the electron configuration. Let's write the electron configuration for this thing anyways, even though it doesn't exist. Okay, let's just pretend. So the electron configuration would be, so sigma one s two. So notice how you write this a little different than how you draw the atomic electron. Sigma star one s. Okay, I know it said if it exists. And this does questions on that. So does that answer your question about anti-bonding electron? Yeah, which, where are those electrons? Pardon? How do you know which electrons are? Which electrons are which, what do you mean? The anti-bonding. So, I mean, do you want to label these one, two, three, four, is that what you're saying? Like these electrons one, two, three, four, and figure out which ones you can't. No, once they get in there, they're all jumbled up, you know? So you can't tell where they came from. These potentially could be these ones too. Okay, and these potentially could be these ones. Or one could be here, one could be here, you know, something like that. So, I mean, you got here, you know, these electrons just flow around, you know? So they're not in really, you know, any one space, okay? Is it top? Yeah, so, okay, yeah, the stars are the anti-bonding, yeah, the ones. So, the bond is, of course, higher or lower in energy than the anti-bonding, okay? So this kind of is forming, right? So even here, right, the atomic orbitals are the higher in energy, right? So that's why bonds form, because the bonding orbital is lower in energy than the atomic orbitals, if you want to think about that. So is that into your question? Okay, sorry, I totally misunderstood your question. And your question is answered too. Cool, cool? Okay, good.
