Eighth most abundant element in the universe. Seventh most abundant element in the earth's crust. Used in alloys to make airplanes, missiles and other uses for light metals. Has structural properties similar to aluminium. But since it is flammable at temperatures of burning gasoline, its uses are limited. Usually obtained by electrolysis of melted magnesium chloride (MgCl2) found in sea water. Each cubic mile of seawater contains about 12 billion pounds of magnesium. Hu385YwuRaM Magnesium
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 12 1755 Sir Humphrey Davy England From the Greek word "Magnesia", a district of Thessaly

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
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.
