'''Sodium''' is an element<ref>Wile, Dr. Jay L. ''Exploring Creation With Physical Science''. Apologia Educational Ministries, Inc. 1999, 2000</ref>in the [[Alkali]] [[metal]]s 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, it reacts violently with water, forming sodium hydroxide and [[hydrogen]] gas.

Its 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.
