In my General Chemisty class, this was one of the homework questions this past week:
What is the formal charge on phosphorus in a Lewis structure for the phosphate ion that satisfies the octet rule?
A: -2
B: -1
C: 0
D: +1
E: +2
The teacher has the answer marked as D: +1, but I get 0 as my answer. I have Phosphorus in the middle with a double bond and 3 single bonds giving it a formal charge of 0.
Am I doing something wrong? Any help would be appreciated
