Description
Soft silvery-white metal. Sixth most abundant element in the earth's crust. Burns in air with a brilliant white flame.
Uses
There are few uses for the pure metal, however its compounds are used in medicine, agriculture and photography. Sodium chloride (NaCl) is table salt. Liquid sodium is sometimes used to cool nuclear reactors.
Sources
Obtained by electrolysis of melted sodium chloride (salt), borax and cryolite.
Pronounciation (English)
SO-di-em
