We'll learn what polyatomic ions are. Polyatomic ions are created when a number of atoms come to together to form a group, and then that group has either a positive or a negative charge, which means that it can be either a cation or an anion. We discuss how protons and electrons balance to give a net charge, and then discuss some common polyatomic ions.
