History
(Gr. bromos, stench) Discovered by Balard in 1826, but not prepared in quantity until1860.
Sources
A member of the halogen group of elements, it is obtained from natural brines fromwells in Michigan and Arkansas. Little bromine is extracted today from seawater, whichcontains only about 85 ppm.
