ETYM New Lat. Related to Potassa, Potash.
A light soft silver-white metallic element of the alkali metal group; oxidizes rapidly in air and reacts violently with water; is abundant in nature in combined forms occurring in sea water and in carnallite and kainite and sylvite.
Soft, waxlike, silver-white, metallic element, symbol K (Latin kalium), atomic number 1atomic weight 39.098It is one of the alkali metals and has a very low density—it floats on water, and is the second lightest metal (after lithium). It oxidizes rapidly when exposed to air and reacts violently with water. Of great abundance in the Earth’s crust, it is widely distributed with other elements and found in salt and mineral deposits in the form of potassium aluminum silicates.
Potassium is the main base ion of the fluid in the body's cells. Along with sodium, it is important to the electrical potential of the nervous system and, therefore, for the efficient functioning of nerve and muscle. Shortage, which may occur with excessive fluid loss (prolonged diarrhea, vomiting), may lead to muscular paralysis; potassium overload may result in cardiac arrest. It is also required by plants for growth. The element was discovered and named in 18by English chemist Humphry Davy, who isolated it from potash in the first instance of a metal being isolated by electric current.
