Bromine (Br ) by %

**Bromine (Br) Element Properties**
Atomic Mass	79.904
Atomic Number	35
Name Origins	Greek, bromos - "stench."
Year Discovered	1826
Discovery Credits	A. J. Balard at Montpellier, France and C. Lowig at Heidelberg in Germany.
Remarks	Deep red, dense, sharp smelling liquid, Br₂. Compounds used in fuel additives, pesticides, flame-retardants, and photography. Bromine is recovered from sea water and oil field brines. Diagnostic tests: Bromine salts (along with F, Cl, and I) will give a blue color to flames when heated on a copper disk. Treatment of the salt with concentrated H₂SO₄ acid will effervesce with the evolution of a brown gas (Br₂). Bromine is always found associated with chlorine or iodine so a precipitate with AgNO₃ solution is white (AgCl), cream (AgBr), or yellow (AgI) depending on which anion predominates.
