History

The chemical abbreviation for sodium was first published by Jöns Jakob Berzelius in his system of atomic symbols. It is a contraction of the element's new Latin name natrium, which refers to the Egyptian natron, a natural mineral salt primarily made of hydrated sodium carbonate. In 1807, Sir Humphry Davy isolated sodium for the first time by electrolysis of dried sodium hydroxide, which had been very slightly moistened. From the English word, soda; Medieval Latin, sodanum: a headache remedy

Discoverers	Sir Humphrey Davy
Discovery Location	England
Discovery Year	1807
Etymology (Name Origin)	Medieval Latin: sodanum, (headache remedy); symbol from Latin natrium, (sodium carbonate).
Pronunciation	SO-di-em (English)

Sodium metal should be handled with great care as it cannot be maintained in an inert atmosphere

Sodium burns in air with a brilliant yellow flame

Uses

Metallic sodium is vital in the manufacture of esters and in the preparation of organic compounds. Sodium vapor lamps are often used for street lighting in cities. Liquid sodium is used as a heat transfer fluid in some fast reactors. Sodium is also used as an alloying metal, an anti-scaling agent, and as a reducing agent for metals when other materials are ineffective. 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.
