The chemical formula that represents a polyatomic ion is **ClO⁻**.
A polyatomic ion consists of two or more atoms covalently bonded together that carry a charge. In this case, ClO⁻ is the hypochlorite ion, which consists of one chlorine atom and one oxygen atom with an overall negative charge. The other options (NaCl, Cl⁻, and Na⁺) represent a neutral compound (NaCl), a monatomic ion (Cl⁻), and a monatomic cation (Na⁺), respectively.
