Lewis Dot Diagramm von Kalzium (Ca)
Description
Fairly hard, silvery-white metal. Fifth most abundant element in the earth's crust (41,500 ppm). Occurs only in compounds.
Uses
Used by many forms of life to make shells and bones. Virtually no use for the pure metal, however two of its compounds are, lime (CaO) and gypsum (CaSO4), are in great demand by a number of industries.
Sources
Obtained from minerals like chalk, limestone & marble. Pure metal is produced by replacing the calcium in lime (calcium carbonate, CaCO3) with aluminium in hot, low pressure retorts.
Pronounciation (English)
KAL-si-em
