Bromine ( or ; from, meaning " stench ( of he-goats )") is a chemical element with the symbol Br, and atomic number of 35.

Bromine is rarer than about three-quarters of elements in the Earth's crust ; however, the high solubility of bromide ion has caused its accumulation in the oceans, and commercially the element is easily extracted from brine pools, mostly in the United States, Israel and China.

Bromine has no essential function in mammals, though it is preferentially used over chloride by one antiparasitic enzyme in the human immune system.

Bromine is slightly soluble in water, but it is highly soluble in organic solvents such as carbon disulfide, carbon tetrachloride, aliphatic alcohols, and acetic acid.

Columbia County, along with Union County, is home to the largest Bromine reserve in the United States.

* Bromine monochloride ( BrCl ) is a red-brown gas with a boiling point of 5 ° C.

* Bromine trifluoride ( BrF < sub > 3 </ sub >) is a yellow-green liquid which conducts electricity — it ionises to form +.

* Bromine pentafluoride ( BrF < sub > 5 </ sub >) is a colourless fuming liquid, made by reacting bromine trifluoride with fluorine at 200 ° C.

Bromine is included as an ozone-depleting chemical because although it is not as abundant as chlorine, it is 45 times more effective per atom in destroying stratospheric ozone.

Bromine ( Br ) has two stable isotopes and 30 known unstable isotopes, the most stable of which is < sup > 77 </ sup > Br with a half-life of 57. 036 hours

Bromine is derived from brine, or saltwater, and local companies play an international role in the commercialization of bromine and its many applications.

Bromine has no known essential role in human or mammalian health, but inorganic bromine and organobromine compounds do occur naturally, and some may be of use to higher organisms in dealing with parasites.

Colour code: Carbon, C: black Hydrogen, H: white Bromine, Br: red-brown Oxygen, O: red Structure calculated with Spartan Student 4. 1, using the PM3 semi-empirical method.

Bromine has two stable isotopes, < sup > 79 </ sup > Br ( 50. 69 %) and < sup > 81 </ sup > Br ( 49. 31 %).

Bromine was discovered independently by two chemists, Carl Jacob Löwig and Antoine Balard, in 1825 and 1826, respectively.

Bromine was not produced in large quantities until 1860.

Bromine atoms are even more efficient catalysts, hence brominated CFCs are also regulated.

In the early 19th century Ignacy Fonberger, a professor at the University of Vilnius, analyzed the chemical composition of Druskininkai's waters and showed that they contain large amounts of Calcium, Sodium, Potassium, Iodine, Bromine, Iron and Magnesium.

* Bromine monofluoride ( BrF ) has not been obtained as a pure compound — it dissociates into the trifluoride and free bromine.
