What is the chemical formula for bromine gas?

Explanation:
Elemental bromine exists as diatomic molecules, so its formula is Br2. In the elemental state, halogens pair up to form two-atom molecules, which is why the gas form of bromine is Br2. The other options show bromine in charged forms or bonded to oxygen (bromide, hypobromite, and bromite), which are not neutral bromine gas.
