bromide

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).
