Description
A corrosive, nonmetallic element. Bromine is a dark, reddish-brown liquid at room temperature. It occurs in seawater at concentrations of about 65 parts per million. Bromine was first identified as a separate chemical element in a 1826 publication by a French chemist Antoint-Jerome Balard. Bromine is used in fumigants, dyes, photographic chemicals, and as a flame retardant in plastics. It is also used for the chemical extraction of gold from ores.
