Carl Jacob Löwig je otkrio brom 1825., dok je još bio student kemije na Sveučilištu u Heidelbergu u Njemačkoj.

Antoine Balard destilirao je brom iz otopine pepela algi zasićene klorom 1824.

Svoje rezultate objavio je 1826., pružajući dokaze da je tvar koju je otkrio novi element. Od grčke riječi bromos, smrad 47 From the Anglo-Saxon word "siolfur" meaning "silver" (the origin of the symbol Ag comes from the Latin word "argentum" meaning "silver")

Bromine is poisonous and causes skin burns
Bromine is the only nonmetallic element that is liquid at ordinary temperatures
Bromine is used in making fumigants, flameproofing agents, water purification compounds, dyes, medicines and sanitizers.

Potassium bromide is used as a source of bromide ions for the manufacture of silver bromide for photographic film.

Bromine is also used to reduce mercury pollution from coal-fired power plants.
