Bromine compound is a molecule formed when two bromine atoms combine together. Bromine (Br2) is a red-brown liquid at ordinary temperature. It is very volatile. It gives very dense red-brown vapours that are highly toxic to mucous membranes. Bromine is purified from the salts taken from rocks and seawater. It is sold as salts or other compounds because pure bromine is expensive and difficult to produce. Bromine was discovered by French chemist Antoine J.Balard in 1826.
