Bromine Chemical Symbol

Introduction to bromine chemical symbol


Bromine is a halogen molecule with the atomic number 35 and bromine chemical symbol is ‘Br’.


Bromine is the only non-metallic element and one of only two elements in the periodic table which appears in liquid state at room temperature and it has melting point of - 7.2 °C and boiling temperature of 58.8 °C. Halogens are a series of non metal elements of group 17 in the periodic table and contain fluorine (chemical symbol is F), chlorine (Cl), iodine (I), and astatine (At) along with bromine (Br). Bromine vapors are dangerous and toxic. In a liquid state, Bromine is corrosive to human tissue and its vapors irritate eyes and throat. Bromine vapors are very toxic with inhalation.

Bromine was discovered by two chemists in the 19th century from the ash of sea weed. Bromine is a diatomic molecule (Br2) in its pure physical form and appears as a dense, mobile, slightly transparent reddish brown liquid. Bromine evaporates easily at standard temperature and pressure and forms a red vapor with a strong unpleasant odor. Bromine reacts vigorously with metals and is considered as a strong oxidizing agent. Bromine has two known stable isotopes and at least 23 other bromine radio isotopes are known to exist. Bromine converts into a metal at a pressure of 55 GigaPascals. Bromine exists as bromide salts in crustal rocks.


Uses of bromine(chemical symbol)


  • Bromide salts are used as anticonvulsants in veterinary and human medicine.

  • Some soft drinks contain brominated vegetable oil.

  • Bromine is used to reduce mercury pollution in power plants.

  • Some bromide salts (potassium bromide for example) are used as photographic developers.

  • Bromide is also used in some water purifying compounds, disinfectants and insecticides.

  • Bromine in the form of Ethydium bromide is used to visualize DNA in gel electrophoresis.

  • Bromine has known significant roles in mammalian health maintenance. For example, bromide ions help in fight against multi cellular parasites like nematodes or certain bacteria.
