Description
Magnesium, the eighth most abundant element in the earth's crust, is a light, moderately hard, silvery-white metal. While ingots of the metal tarnish in air and react very slowly with water, finely divided powder is very reactive. Magnesium does not occur uncombined, but is found commonly in magnesite, dolomite, and other minerals. It is the lightest of the structural metals, (a third lighter than aluminum) making it essential as an alloy in airplane and missile construction.
