Bromine Formula

Bromine formula

Bromine is known to be a chemical element that is denoted by symbol Br. In this article, we’ll learn about the Bromine formula.

Bromine element is known to be the third lightest halogen as well as a volatile red-brown liquid at room temperature. The formula of Bromine is Br₂. Carl Jacob Lowing along with Antony Ballard are known to discover the Bromine element in 1825 and 1826 respectively. Bromine doesn’t look like a free element. The major reason behind this is that it is always joined with other elements.

Bromine is known to be well-distributed among rocks, water, soils, animal tissues, plants as well as foodstuff. The most common salts are considered as bromides, organic and inorganic. Usually, Bromine is found in low quantities in freshwaters. However, it is found in large quantities in seawater. The derivatives of Bromine are utilized in end-use industries. 

Bromine is used to prepare Bromine compounds. The production of Bromine takes place on a Global level. Examples of Bromine compounds include methyl bromide, silver bromide, lithium bromide, etc.
