Polyatomic ions are molecules or groups of atoms that carry a net electrical charge. They are formed when two or more atoms are covalently bonded together, but the overall molecule has gained or lost electrons, resulting in a positive or negative charge. Here's a more detailed explanation: Covalent Bonding: Polyatomic ions are held together by covalent bonds, where atoms share electrons to achieve stability. Net Charge: Unlike molecules, which are electrically neutral, polyatomic ions have a net
