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. From the Greek word bromos, stench 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.
