1.a soft, silver-white, chemically active metallic element that occurs naturally only in combination: a necessary element in the body for the maintenance of normal fluid balance and other physiological functions.Symbol:Na;at. wt.:22.9898;at. no.:11;sp. gr.:0.97 at 20°C. ...
So called because the element was isolated from caustic soda (sodium hydroxide). The chemical symbol Na is from natrium, the name for the element that had been proposed by Berzelius and coined from natron, a name of a type of soda.

Sodium is the sixth most abundant element in The Earth’s crust, which contains 2,83% of sodium in all its forms. Sodium is, after chloride, the second most abundant element dissolved in seawater. The most important sodium salts found in nature are sodium chloride (halite or rock salt), ...
[54] also found Na element on the surface of Fe-Mn-Si alloplastic implants besides common Ca and P elements. Despite all that, none of the studies attributed the Fe implants’ corrosion to the presence of Na+, most probably due to its very low amount on the corroded Fe surface as ...
