 To what? To draw where it's forward and back. And you should get used to that. Let's just do it together. Do an end drawing of bottom angle speed. I would, yeah. Because this has a different bottom angle because it's only got the one lone pair. It's different than methane or water. So let's draw something that's got four electron pairs, three bottoming pairs and one lone pair. So that's going to be something that looks like this. So we're going to have, it's going to need five electrons around it because it's going to have one, two, three, four, five like that. So these three can bond and that one's going to be the lone pair. Is everybody cool with that? So what looks like that? We've looked on the periodic table. We count the electrons. One, two, three, four, five. Which one is it? It's nitrogen, right? No, it's not ex anymore. It's not some unknown atom. It's nitrogen. And since we've been doing these as only one central atom, all the other ones, we're just going to have this hypo. Having one central atom, right? So when that happens, what do we get? Or in H3, have four electron pairs around it? Yes, right? It's got three bottoming pairs. It's got one lone pair. It's going to be tetrahedral, right? Because you've got those four pairs around each other, around that one central atom. If it's tetrahedral electronically and it's got one lone pair, then it's going to look like this. I don't erase this part. It's going to look like the bottom. So what is the bottom of methane? Look forward bond. You've got the hash bond. You've got the bond in the plane right there. So remember, if this was methane, that bond angle would be what? 109 and 1 half, right? But since we've got a lone pair here, remember what we said about water? It was more diffuse, right? So it pushes those bonds down more. But it doesn't push them as much as two lone pairs would, like in water. So instead of being 109 and 1 half or 104 and 1 half, it's somewhere in the middle, OK? Yeah, it's going to be 107.3. So that bond angle is 107.3. And then the molecular geometry, as you can see, remember, if you were looking at just the molecule and not the electron shape, right, you wouldn't see this part. So this looks like a pyramid, right? A three-sided pyramid. So we call this. Sure you're going to know all the questions about that one? Any questions? I do have a question, but it's not necessarily relevant to it. So this question here? Yes. So what you're talking about, I don't know. I have a different question. OK, let's have it. Is there any questions on this? Problem ammonia? OK, cool.
