WebPolyatomic Ions • Polyatomic ions are groups of two or more bonded atoms that have lost or gained electrons, and thus have an overall net charge. • Examples Carbonate ion, CO 3 2 –, has one C atom bonded to three O atoms. It has gained two electrons for a − 2 charge. Ammonium ion, NH 4 +, has one N atom and four H atoms.
