Calcium - Periodic table
Calcium is reactive and, for a metal, soft. With a bit of effort, it can be cut with a sharp knife. In contact with air, calcium develops a mixed oxide and nitride coating, which protects it from further corrosion. Calcium reacts easily with water and acids and the metal

Pure chlorine, both as a gas and as a liquid under pressure, reacts with only a few metals at ordinary temperatures. For this reason, chlorine may be safely stored in metal containers. Moist chlorine, however, corrodes most metals rapidly and a solution of chlorine in water has powerful oxidizing, bleaching and germicidal properties.
