Chlorine

Chlorine

        Chlorine is (at room temperature) a greenish-yellow gas that can be readily liquefied at 5170 Tarr or 6.8 atmospheres, at 20 C (68 F), and has a very disagreeable odor. Its Element symbol is Cl, atomic number is 17, and atomic mass is 35.453. Chlorines melting come in is -101 C or 149.8 F. The boiling point is -34.05 C or -29.29 F, at star atmosphere pressure. Chlorine is a sh are of the halogen group. Chlorine was discovered by Swedish scientist Karl Wilhelm in 1784, scarcely he first thought it was a compound, rather than an element. In 1810, Sir Humphrey Davy named it Chlorine, from the Greek word meaning greenish-yellow.

        Chlorine is used in bleaching agents, disinfectants, monomers (plastics), solvents, and pesticides. It is also used for bleaching paper pulp and other thoroughgoing materials, preparing bromine, (a poisonous element that at room temperature is a dark, reddish-brown), tetraethyl lead, and cleaning germs in water, particularly in swimming pools and hot tubs.

Like each member of the halogen group, chlorine has a tendency to gain one electron and become a chloride ion. Chlorine strongly reacts with metals to imprint mostly water-soluble chlorides. Chlorine also strongly reacts with nonmetals such as sulfur, phosphorus, and other halogens.



If you were to mix hydrogen and chlorine gases and support them in a cool dark place, the mixture would be stable, but if it were exposed to sunlight, it would cause a strong explosion. If a burning candle were placed in a plastered container of chlorine, it would keep burning, and it would produce thick, black, smoke, leaving behind soot. There are five oxides that chlorine can form: chlorine monoxide; dichloride monoxide; chlorine dioxide; chlorine heptoxide; and chlorine hexoxide.
