Br2 (bromine) is classified as a molecular compound. This classification comes from the fact that Br2 consists of two bromine atoms that are covalently bonded together, sharing a pair of electrons.
Ionic compounds typically form between metals and nonmetals, where electrons are transferred from one atom to another, resulting in the formation of charged ions. In contrast, in molecular compounds like Br2, nonmetals share electrons to achieve stability, which is characteristic of covalent bonding.
Because bromine is a nonmetal, and Br2 contains only bromine atoms, this compound fails to meet the criteria for ionic bonding. Moreover, Br2 is a diatomic molecule, existing as a gas at room temperature, and its properties align perfectly with those of molecular compounds.
