Bromine is a halogen element. It becomes red volatile liquid at room temperature. Bromine reactivity is somewhere between chlorine and iodine. Harmful to human tissue in a liquid state, its vapour irritates eyes and throat. Bromine was discovered by Antoine Balard in 1826. Bromine has 30 isotopes, 2 of them are stable and naturally occurring.
Bromine was once used in large quantities to make a compound that removed lead compound build up in engines burning leaded gasoline. Now it is primarily used in dyes, disinfectants, and photographic chemicals.
