Tarix
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.

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.
