Description
Calcium. Jar of elemental calcium pellets. Calcium (Ca) is a reactive metallic element. It is classified as an alkaline earth metal, as are magnesium and barium. Although it is silver-white, it rapidly tarnishes on exposure to air, turning brown as seen here. Calcium metal is used in the manufacture of alloys and in casting. Its many compounds are important in industry. In the body, calcium is essential for the formation of bones and teeth, and calcium ions are important in blood clotting, regulation of the heartbeat, cell signalling and many other biochemical processes.
