Okay, so here you want to draw the blue structure of n2h2.
00:04
So in order to do this, first we need to know how many valence electrons we have.
00:08
So each hydrogen has one valence electron, we have two of them, and then nitrogen have five valence electrons, and we have two of them.
00:17
So overall, there's going to be 12 electrons in our structure.
00:22
So then what you want to do is just go ahead and draw the skeleton.
00:25
And so we put our two, we put our least electronegative atoms besides hydrogen, middle.
00:30
And the only other atoms we have here are nitrogen.
00:34
And then because we have two hydrogens, let's just go ahead and make this as simple as possible and make it a symmetrical molecule.
00:41
So now we've drawn the skeleton structure.
00:44
And we've used up three bonds to do that, which means that we've used up six electrons so far.
00:51
So now we have six more electrons to put into our structure, and we need to make sure everything has a cool octet.
00:57
So in order to do that, each of the nitrogen's right now has four electrons, so each of them need four more electrons...
