A bromide is a chemical compound containing a bromide ion or ligand. This is a bromine atom with an ionic charge of −1 (Br⁻); for example, in caesium bromide, caesium cations (Cs⁺) are electrically attracted to bromide anions (Br⁻) to form the electrically neutral ionic compound CsBr. The term "bromide" can also refer to a bromine atom with an oxidation number of −1 in covalent compounds such as sulfur dibromide (SBr₂).
