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). |
