calcium (Ca) - David Darling

Calcium (Ca) is a soft, gray, metallic element that tarnishes rapidly on exposure to air. Calcium is one of the alkaline earth metals. It occurs commonly on Earth (see elements, terrestrial abundance ), in various forms of its carbonate (CaCO 3 ), e.g., chalk, limestone, marble, and calcite, and its sulfate (CaSO 4 ), e.g., gypsum.
