Secrets of Calcium

image of periodic table symbol for calciumDid you know that pure calcium is a silver-gray metal that is soft enough to easily cut with a knife? It burns with an intense red flame, and when in powered form it reacts violently with water to release free hydrogen.

 

Although one of the most common elements on Earth, it is never found in its pure form in nature because it reacts so readily with oxygen and water. It combines with other elements to form such key minerals and rocks such as chalk, gypsum, limestone and marble.

 

Another secret of calcium is that each adult human body contains more than 2# of calcium. Out of the two pounds – teeth and bones contain more than 99%. Calcium is also important in the functioning of nerves and muscles.
