Sodium (play /'so?di?m/ soh-dee-?m) is a chemical element with the symbol Na and atomic number 11. It is a soft, silvery-white, highly reactive metal and is a member of the alkali metals; its only stable isotope is 23Na. Elemental sodium was first isolated by Humphry Davy in 1807 by the electrolysis of sodium hydroxide. It does not occur naturally on Earth, instead quickly reacting in air[2] and water, so it must be stored in a non-oxidizing medium such as a liquid hydrocarbon. The free metal is used for some chemical syntheses, analyses, and heat transfer applications. The Na+ ion is soluble in water, and is thus present in significant quantities in the Earth's bodies of water; here, it is neutered by the chloride ion, causing evaporated ocean water solids to consist mostly of sodium chloride. The same ion is also a component of many minerals, such as sodium nitrate. Due to this solubility of the sodium ion in water, it is relatively scarce on land, and gets leached into water by rainfall. Sodium is an essential element for all animals and some plants. In animals, sodium ions are used against potassium ions to build up charges on cell membranes, allowing transmission of nerve impulses when the charge is dissipated; hence, it is thus classified as a dietary inorganic macro-mineral. source: http://en.wikipedia.org/wiki/Sodium |
