Brom

BROMINE: HISTORY, NAME AND APPLICATION *Bromine (German: Bromt) is a chemical element of group VIIA of the periodic table of chemical elements, a monatomic molecular gas with an atomic mass of 79.904 and a melting point of -7°C. Bromine was discovered by Swedish chemist Jons J. Berzelius in 1809.*

The name of the element Bromine comes from the Greek word "bromos" (foul-smelling substance). It is associated with the unpleasant odor of ethyl bromide, which was accidentally discovered by researchers in sodium bromide.

Bromine has a lower melting point than metals such as lead and mercury. This allows it to easily evaporate from compounds and enter into compounds at room temperature. For example, this property of bromine is used to detect lead residues in water or alcoholic beverages. In addition, bromine compounds are used in drying and air purification. When bromine reacts with carbon dioxide, hydrogen bromide is formed. Aqueous solutions of bromine are used to disinfect water. Bromine is also included in many medicines.
