Halogens, in chemistry, group of five closely related chemical elements: fluorine, chlorine, bromine, iodine, and astatine. Each of the halogens has the property of forming with sodium a salt similar to common salt, sodium chloride.

Chlorine
Chlorine, symbol Cl, greenish-yellow gaseous element with an atomic number of 17 and an atomic weight of 35.453. Chlorine is one of the halogens. It has an irritating odor and in large concentrations is dangerous; it was the first substance used as a poisonous gas in World War I (1914-1918) (see Chemical and Biological Warfare).
Chlorine does not occur alone in nature, but its compounds are common minerals, including ordinary salt. Chlorine reacts with water, organic compounds, and many metals. It will not burn in air, but it will support the combustion of many substances. Chlorine and hydrogen can be kept together in the dark, but react explosively in light. Chlorine and water solutions are used as household bleach. Chlorine is used for bleaching paper pulp, as a germicide in water, and in preparing bromine, tetraethyl lead, and other important products.
