What is the difference between calcite and calcium

Calcite is a carbonate mineral and the most stable polymorph of calcium carbonate (CaCO3) The Mohs scale of mineral hardness based on scratch hardness comparison defines value 3 as 'calcite' Other polymorphs of calcium carbonate are the minerals aragonite and vaterite
