Chlorine The elements name is chlorine The atomic number is 17 The atomic symbol is Cl

History It was discovered in 1774 by Scheele, who thought it contained oxygen, chlorine was named in 1810 by Davey who decided it was an element. It was discovered by Carl Wilhelm Scheele It name came from the Greek word khlôros which means green

Uses In nature chlorine is only found in the combine star with sodium. In other words it is only found in salt. The other used in making many everyday products. It is supplies are now usually chlorinated.

Other Uses It is also extensively used in the production of paper products, dyestuffs, textiles, petroleum products, medicines, antiseptics, insecticides, food, solvents, paints, plastics, and many other consumer products

More Uses Most of the chlorine produced is used in the manufacture of chlorinated compounds for sanitation, pulp bleaching, disinfectants, and textile processing. Further use is in the manufacture of chlorates, chloroform, carbon tetrachloride, and in the extraction of bromine

Finally Uses Organic chemistry demands much from chlorine, both as an oxidizing agent and in substitution, since it often brings many desired properties in an organic compound when substituted for hydrogen, as in one form of synthetic rubber

Facts Chlorine crystal structure is Orthorhombic Chlorine’s color is green Chlorine’s melting point is -149.764 °F and it’s boiling point is -30.279997 °F

Sodium The element’s name is sodium The element’s atomic number is 11 The element’s symbol is Na

History Long recognized in compounds, sodium was first isolated by Davy in 1807 by electrolysis of caustic It was discovered by Sir Humphrey Davy It’s name came from soda (Na2CO3)

Found in Nature Sodium is found in nature in fair abundance in the sun and stars. The D lines of sodium are among the most prominent in the solar spectrum. Sodium is the fourth most abundant element on earth, comprising about 2.6% of the earth's crust; it is the most abundant of the alkali group of metals

Found in Nature Also it is now obtained commercially by the electrolysis of absolutely dry fused sodium chloride. This method is much cheaper than that of electrolyzing sodium hydroxide, as was used several years ago

Uses Metallic sodium is vital in the manufacture of esters and in the preparation of organic compounds. The metal may be used to improve the structure of certain alloys, descale metal, and purify molten metals Also an alloy of sodium with potassium, NaK, is an important heat transfer agent

Facts Sodium crystal structure is cube Sodium color is silvery Sodium melting point is 208.04001 °F and it’s boiling point is 1027.2201 °F
