Which statement correctly identifies a diatomic halogen molecule?

Explanation:
Halogens in their elemental form pair up to achieve a full outer shell, so they exist as diatomic molecules (two atoms held together by a covalent bond). Chlorine, bromine, and iodine each form such two-atom molecules: Cl2, Br2, and I2. Because all three listed halogens are diatomic in their elemental state, the statement that describes a diatomic halogen molecule is correct for each of them. For broader context, fluorine and astatine also form diatomic molecules (F2 and At2), illustrating the same pattern across the halogen group.
