Most of the common inorganic polyatomic ions have negative charges. This means the ion has more electrons than the neutral atoms that are in the ion. A polyatomic ion like phosphate, PO43- has three extra electrons beyond the electrons on the P and O atoms. Got this off google sorry if it doesn't help you :(
