 Okay guys, so let's try the first one that I see here. Do you notice that F2, so it gives you already the molecular structure, okay? So what I want you to do is take the atomic structure of F or two individual Fs and show how they form that bond to make F2, okay? Do it not only with your model kit but also on a piece of paper drawing. It's more important because of course on the test you're going to have to show me through drawing, okay? So I'll do it up here and you do it on your own and see if you get the similar answer, okay? Again, it does much better good for you guys if you do it on your own prior to looking up and seeing what I've done, okay? So the first thing I would do is put an F, look at the periodic table, look where F is on the periodic table, realize that it's a halogen, right? Group 7 or 17. It's going to have seven valence electrons around it. How do I draw them? One, well, let's draw them this way. One, two, three, four, five, six, seven. So it's missing one electron, we know that. The other fluorine is exactly the same, okay? Bless you. Then I realize, well, it only needs one electron to fill its octet. Not to mention these are both nonmetals, okay? I know that the bond that occurs between a nonmetal and a nonmetal is a covalent bond. A covalent bond means what? They're sharing, okay? So remember how we show sharing of electrons? We take one and we show that little fish hook arrow like that. The other one, show the little fish hook arrow like that. And instead of having all of this, what's our product going to look like? Why does it look like this? Because when we're drawing molecules, we depict a shared pair of electrons as a straight line in between the two atoms that are sharing it or covalent bond, we call that. And we depict the lone pairs as pairs of electrons around the atomic symbol, okay? So is everybody clear on this is how I would build this F2 molecule? Do you think you could build it on your own? I bet you could. Could you tell me a molecule that's very similar in structure to F2? H2, yeah, that is. That's not the one I was thinking of. I was thinking of which one? I2. That would be a very similar one. Or Cl2, right? Or Br2, any of the halogens. H2 would be also similar, too, because they both need one electron in their valence shell, but H2 only doesn't have the lone pair electrons, okay? So in some respects, it's similar in others, it's not, so, okay? Everybody okay? Can I shut off the video? Okay, cool.
