Sodium
Life could not exist without compounds of sodium. These compounds hold
water in body tissues, and a severe deficiency of sodium can cause death.
Blood contains sodium compounds in solution. Sodium compounds are used in
industry in the manufacture of chemicals and pharmaceuticals, in metallurgy,
in sodium vapor lamps, and in the production of hundreds of every day
products. One of the most common sodium compounds is table salt, or sodium
chloride. In its pure form sodium is a silver-white, soft and waxy metallic
element. It is the sixth most abundant element on Earth and occurs in more
that trace amounts in the stars and sun.
