a) Ionic; because polyatomic ions are composed of a metal and a nonmetal.
b) Covalent; because polyatomic ions are composed of two or more nonmetals sharing electrons.
c) Ionic; because polyatomic ions are composed of two or more atoms with a net positive or negative charge.
d) Covalent; because polyatomic ions involve the sharing of electrons between atoms.
