Hi there.
00:03
In this question, we need to start out by drawing the lewis structure for br, cl4 with a negative charge.
00:11
All right.
00:11
So let's go ahead and sketch that out, where you're going to put bromine in the center, surrounded by the four chlorines.
00:23
Each chlorine is a halogen.
00:25
So each chlorine has seven valence electrons.
00:41
All right.
00:42
Bromene is also a halogen.
00:46
So it has seven valence electrons.
00:47
Electrons, but then we have that unit of negative charge.
00:53
So that means we still have eight electrons to put in.
00:56
And i'm just going to alter the color just so we can see those eight electrons.
01:01
So four of them are going to be used for the single bond with each chlorine.
01:07
And then that leaves us four more electrons.
01:10
So there are going to be two lone pairs on the bromine.
01:15
So look what we have here.
01:16
We have four atoms bonded...
