Description
A nonmetallic halogen element. Chlorine has an abundance of 0.031% in the earth's crust (Halite, sylvite, carnallite) and 1.9% in seawater (chloride salts). It was discovered in 1774 by Carl Wilhelm Scheele and recognized as an element by Sir Humphrey Davy in 1810. Chlorine exists at room temperature as a greenish-yellow gas with a suffocating odor. It was used as a poisonous gas in World War I called Bertholite. Chlorine is used for bleaching paper pulp, as a germicide in water, and for the synthesis of numerous organic compounds.
