ETYM New Lat., from Latin calx, calcis, lime; cf French calcium. Related to Calx.
Soft, silvery-white metallic element, symbol Ca, atomic number 2atomic weight 40.0It is one of the alkaline-earth metals. It is the fifth most abundant element (the third most abundant metal) in the Earth’s crust. It is found mainly as its carbonate CaCOwhich occurs in a fairly pure condition as chalk and limestone (see calcite). Calcium is an essential component of bones, teeth, shells, milk, and leaves, and it forms 1.of the human body by mass.
Calcium ions in animal cells are involved in regulating muscle contraction, blood clotting, hormone secretion, digestion, and glycogen metabolism in the liver. It is acquired mainly from milk and cheese, and its uptake is facilitated by vitamin D. Calcium deficiency leads to spasming of the muscles (tetany); an excess of calcium may lead to the formation of stones (see calculus) in the kidney or gall bladder.
The element was discovered and named by the English chemist Humphry Davy in 180Its compounds include slaked lime (calcium hydroxide, Ca(OH)2); plaster of Paris (calcium sulfate, CaSO4.2H2O); calcium phosphate (Ca3(PO4)2), the main constituent of animal bones; calcium hypochlorite (CaOC12), a bleaching agent; calcium nitrate (Ca(NO3)2.4H2O), a nitrogenous fertilizer; calcium carbide (CaC2), which reacts with water to give ethyne (acetylene); calcium cyanamide (CaCN2), the basis of many pharmaceuticals, fertilizers, and plastics, including melamine; calcium cyanide (Ca(CN)2), used in the extraction of gold and silver and in electroplating; and others used in baking powders and fillers for paints.
