Calcium - Wikipedia

Calcium is a chemical element with the syol Ca and atomic nuer 20. As an alkaline earth metal, calcium is a reactive metal that forms a dark oxide-nitride layer when exposed to air. Its physical and chemical properties are most similar to its heavier homologues strontium and barium. It is the fifth most abundant element in Earth''s crust

Calcium - MMTA

2016/6/24· Calcium, when in contact with air, decomposes quickly into calcium hydroxide and calcium carbonate, which are both chalky, white substances. On contact with water or acid, calcium metal generates hydrogen gas, similarly to the Alkali Metals of Group 1, but does so at a slower, more controlled pace, making it a useful source of small amount of hydrogen.
