If a polyatomic ion contains a -3 charge, what is the sum of oxidation numbers for that ion?

Explanation:
Oxidation numbers inside a polyatomic ion add up to the ion’s overall charge. If the ion carries a -3 charge, the sum of all the oxidation states must be -3. So the total oxidation-number sum is -3. A sum of 0 would mean a neutral species, +3 would indicate an overall positive ion, and -1 would correspond to a singly negatively charged ion with charge -1.
