What oxidation states can bromine have?

Bromine exhibits several oxidation states, with -1 being the most stable state in which it occurs naturally. In addition to this, bromine is known to exist in the following oxidation states: 0, +1, +3, +4, +5, and +7.123

These states are characterized as follows:
* 0: Elemental bromine (${\text{Br}}_2$).13
* +1: Found in hypobromite (${\text{BrO}}^{-}$).1
* +3: Found in bromite (${\text{BrO}}_2^{-}$).1
* +4: Bromine is also known to exhibit this oxidation state.13
* +5: Found in bromate (${\text{BrO}}_3^{-}$).1
* +7: Found in perbromate (${\text{BrO}}_4^{-}$).1

Compounds containing bromine in positive oxidation states are typically stabilized by appropriate ligands, primarily oxygen and fluorine, and these compounds contain covalent bonds.1
