Na - Sodium

Sodium (aka natrium) is a ubiquitous, alkali metal. Humphrey Davy electrolysed pure sodium from sodium hydroxide in 1807 in London. Soap is generally a sodium salt of fatty acids. The importance of common salt to animal nutrition has been recognized since prehistoric times. The most common compound is sodium chloride, (table salt).
