Answer: Calcium

Calcium in its pure form is a dull gray colored alkaline metal that looks more like the remains of a futuristic robot than the kind of white mineral-like substance that most of us imagine when we knock down glasses of milk in an attempt to build strong bones.

It is also the most common metal in the human body, both found in ionic form (necessary for metabolic functions) and in its more well-known bones and teeth as hydroxyapatite – the mineral form of calcium that is half the weight of our includes bones and most of our teeth. Calcium is so abundant in the human body, in fact, that almost all ash residues from a cremation are based on calcium, such as calcium phosphate.
