In this problem, we're looking at a chloride ion, so clo2 minus.
00:06
And we want our electron geometry as well as our molecular geometry.
00:13
So first we're going to look at how many balance electrons we have.
00:17
Chlorine has seven.
00:19
Each oxygen has six.
00:21
And that minus one charge means we add one more electron.
00:25
So we get 20 electrons here.
00:30
And a nice trick you can do is say, all right, there's two outer atoms, each needs an octet, so we get 16 electrons.
00:40
And you'll notice there has a four electron difference.
00:43
That tells us that four electrons go in our central atom chlorine.
00:47
So we see those two lung pairs.
00:51
And we can start with single bonds to oxygen.
00:55
And if we followed the octet rule, this is what we would leave it like...
