An Introduction to Calcium Metal - MMTA

13/04/2016· Although calcium is the fifth most abundant element (and 3rd most abundant metal) in the earth’s crust, present at a level of about 3% in the oceans and soil, it is never found free in nature. Calcium easily forms compounds by reacting with not only air but also with water and acid (on contact with water or acid, hydrogen gas is made in a fairly controlled manner, in comparison to the other alkali metals).
