In this problem, we're looking at formal charges in each of these resonant structures.
00:06
So all of our hydrogens look the same here.
00:10
They have one balance electron and one bond.
00:12
So the formal charge is zero for each of these.
00:17
Now, if we look at our first carbon, carbon has four balanced electrons.
00:22
Here it has two bonds and four electrons.
00:24
So we get negative two.
00:28
Nitrogen has five valance electrons, four bonds, and no extra electrons.
00:33
So we have plus 1.
00:37
And oxygen has 6 valance electrons, 3 bonds, and 2 electrons.
00:43
So we have plus 1.
00:47
Over here, carbon has 4 valance electrons, 4 bonds and no extra electrons.
00:53
So we have 0.
00:55
Nitrogen has 5 balance electrons, 4 bonds and no extra electrons.
00:59
So we get plus 1...
