Bromine (pronounced /ˈbroʊmiːn/ BROH-meen or /ˈbroʊmɨn/ BROH-min, from Greek: βρῶμος, brómos, meaning "stench (of he-goats)" ), is a chemical element with the symbol Br and atomic number 35. A halogen element, bromine is a reddish-brown volatile liquid at standard room temperature that is intermediate in reactivity between chlorine and iodine. Bromine vapors are corrosive and toxic. Approximately 556,000 metric tonnes were produced in 2007. The m...

Bromine (pronounced /ˈbroʊmiːn/ BROH-meen or /ˈbroʊmɨn/ BROH-min, from Greek: βρῶμος, brómos, meaning "stench (of he-goats)" ), is a chemical element with the symbol Br and atomic number 35. A halogen element, bromine is a reddish-brown volatile liquid at standard room temperature that is intermediate in reactivity between chlorine and iodine. Bromine vapors are corrosive and toxic. Approximately 556,000 metric tonnes were produced in 2007. The main applications for bromine are in fire retardants and fine chemicals.
Bromine was discovered independently by two chemists Antoine Balard and Carl Jacob Löwig in 1825 and 1826.
Balard found bromide salts in the ash of sea weed from the salt marshes of Montpellier in 1826. The sea weed was used to produce iodine, but also contained bromine. Balard distilled the bromine from a solution of seaweed ash saturated with chlorine. The properties of the resulting substance resembled that of an intermediate of chlorine and iodine, with those results...
