Bromine is a fuming red-brown liquid at room temperature that evaporates readily to form a similarly colored gas.
Core Principles & Analysis
Antoine-Jerome Balard isolated bromine from Montpellier salt-marsh brine in 1826, naming it from the Greek for 'stench'.
It is one of only two elements liquid at room temperature, alongside mercury, forming a dense red-brown liquid that fumes corrosively.
Brominated compounds serve as flame retardants and drilling fluids, silver bromide made photographic film light-sensitive, and the ancient dye Tyrian purple is a natural organobromine.
