what is the chemical name of calcium ca? - EAS
- CalciumCalcium is a chemical element with the symbol Ca and atomic number 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.Appearance: dull gray, silver; with a pale yellow tintBoiling point: 1757 K (1484 °C, 2703 °F)CAS Number: 7440-70-2
