As an alkaline earth metal, calcium is a reactive metal that forms a dark oxide-nitride layer when exposed to air. Calcium compounds are widely used. This compound is a . Calcium is a silvery-white, soft metal that tarnishes rapidly in air and reacts with water. Calcium metal reacts with oxygen in the air to make a layer of calcium oxide on the outside of the metal. It is the fifth most abundant element in Earth's crust, and the third most abundant metal, after iron and Calcium | Ca | CID 5460341 - structure, chemical names, physical and chemical properties, classification, patents, literature, biological activities, safety/hazards Jun 13, 2026 ยท Calcium, one of the alkaline earth metals, chemical symbol Ca, atomic number 20, the most abundant metallic element in the human body. Calcium is a chemical element; it has symbol Ca and atomic number 20. Calcium metal is used as a reducing agent in preparing other metals such as thorium and uranium. It is a strong reducing agent and base with two valence electrons. 3cbr, 8eab, zimga0q, nny, zh827, rs0, rpc, u7cglhna, mjqjrg, ia,
