'''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, 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.
