Hi there.
00:03
The formal charge for an element is calculated by taking the elements number of valence electrons and then subtracting the sum of the number of electrons in lone pairs plus one half the bond of electrons.
00:19
So we are told we have a sulfur atom with one lone pair.
00:27
So black dots equals lone pair.
00:33
And then three single bonds.
00:36
So this thing has three.
00:36
Single bonds and one loan pair.
00:44
So two blue dots are going to represent a single bond here.
00:49
Okay, so i think we're ready to calculate the formal charge.
00:54
So formal charge, i'm just going to abbreviate fc for formal charge of the sulfur.
01:00
We need to take sulfur's valence electrons.

Sulfur is in group six on the periodic table...
