### When would a compound not have FC=0?

Like the title says, what would the conditions have to be for a formal charge to be greater than or less than 0?

If a compound has a charge, one or more of the atoms involved will have a formal charge not equalling 0. That being said, if this case scenario is encountered, make sure the charged atoms are energy stable. For example, If you have SO3 2 minus, the negative formal charges should be on the oxygens, since their electronegativity allows them to maintain stability while having a negative formal charge.

It would be when the compound itself is charged/a polyatomic ion.To add on to the previous answer, since SO32- has a 2- charge overall already, the formal charges (if correctly calculated) should also come out to -2.
