Sodium is an element[1]in the alkali metals class of the periodic table. It is so chemically active that it is never found free (in elemental form) in nature. In its elemental form, sodium reacts violently with water, forming sodium hydroxide and hydrogen gas. Sodium metal is usually stored in an oil based solution to prevent it from reacting with moisture in the air.
Sodium's existence, as salt (sodium chloride), "soda ash" or "mineral alkali" (sodium carbonate), lye or "caustic soda" (sodium hydroxide), etc., had long been known, but it was not isolated as an element until 1807, by Sir Humphrey Davy.
