Bromine : Description and use

Description

Dibromine is a molecule comprising two bromine atoms. It is the only molecular form (allotrope) of the element bromine.
It is a highly volatile red liquid. It is extremely toxic if inhaled and causes serious burns. The vapours attack the mucous membranes, the skin and the respiratory system. Its aqueous solution is called "bromine water" and is far less harmful.
