Bromide
= Bromide
<Bromide> is the anion $\mathrm{Br^-}$, formed by reduction of bromine or present in bromide salts. In water it is a solvated ion, rather than a free bromine atom with unchanged electronic structure.
It can act as a ligand or nucleophile and participates in redox chemistry. A covalent organic bromide contains a carbon-bromine bond, so the word's chemical context distinguishes an anion from a class of organobromine compounds.
