Calcium - Wikipedia

Calcium is reactive and, for a metal, soft (with difficulty, it can be cut with a 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 burns brightly in air, forming mainly the nitride.
