Calcium is found in nature primarily in the form of compounds such as calcium carbonate (in limestone and marble), calcium sulfate (in gypsum), and calcium phosphate (in bones and teeth). It can also be found in various minerals and in seawater.
Calcium phosphate and calcium carbonate are found in bones .
Calcium is usually found in compounds rather than as a pure element. Common calcium compounds include calcium carbonate (found in limestone and eggshells) and calcium hydroxide (used in cement and as a food additive).
Calcium is found in the matrix of bone.
Calcium and phosphorus are the two major elements found in milk.
Calcium oxide (CaO) contain calcium and oxygen.
Calcium and carbon are the main elements found in calcium carbide. The chemical formula for calcium carbide is CaC2, indicating one calcium atom and two carbon atoms in each molecule.
The element calcium is found in all four items.
Calcium carbonate is made of the elements calcium, carbon, and oxygen.
