Things to know about the Dormant Bromine

Dormant bromine is the name given to the chemical element Br. It is one of the best of all known chemical elements, and has many uses. One example is its use in making paper, which makes it useful for writing on. Another example is its use in photography, which makes it useful for taking pictures. Bromine is also used in some medicines, such as those that are used to treat stomach problems and those that are used to treat coughs. There are no known natural sources of bromine, so it must be made by people in chemical laboratories. It can be made by combining chlorine with other elements.

Most bromine is produced commercially from brines containing the element, which are found in the Dead Sea and in underground pools in Michigan, Arkansas, and elsewhere. Bromine and its compounds are used as flame retardants for textiles, plastics, and paints; as pesticides for soil and water treatment; as fumigants for grain products; in well-drilling fluids; in photography; in medicines; and as disinfectants.

Bromine is a chemical element with symbol Br and atomic number 35. It is the third-lightest halogen, and is a fuming red-brown liquid at room temperature that evaporates readily to form a similarly coloured gas. Its properties are thus intermediate between those of chlorine and iodine. Isolated independently by two chemists, Carl Jacob Löwig and Antoine Jerome Balard, its name was derived from the Ancient Greek βρῶμος (“stench”), referencing its sharp and disagreeable smell.

Elemental bromine is very reactive and thus does not occur free in nature, but in colourless soluble crystalline mineral salts, occurring mainly as the crystalline hydrate sea salt form, sodium bromide. The free element is used exclusively in combination with other elements (for example, in organobromides), with about half of all bromine production used in the manufacture of organic chemicals. The first commercial bromide mineral was bromyrite (bromide-bismuth sulfide) discovered on the Bolivian silver island Cerro Rico de Potosi in 1823.

Bromine is a chemical element that has the symbol Br and atomic number 35. It is a halogen. Bromine is in the halogen group (17) of elements. The element is obtained by extraction from brines, but it can also be prepared synthetically. The name bromine was given to this element in 1826 by Jöns Jacob Berzelius; the name comes from the Greek word bromos meaning “stench.”

In nature, bromine occurs only as a dissolved salt and never as the free element. It resembles chlorine chemically, but is much less active in displacing hydrogen from acids or bases. In compounds and as free atoms, bromine has both oxidizing and reducing properties.
