Sejarah
Carl Jacob Löwig discovered bromine in 1825, while still a chemistry student at Heidelberg University, Germany.

Antoine Balard distilled the bromine from a solution of seaweed ash saturated with chlorine in 1824.

He finally published his results in 1826, providing evidence that the substance he had discovered was a new element.

Aplikasi
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.
Bromine is poisonous and causes skin burns
