Yes. Calcium is an element, and it has the atomic number 20 and Ca is its chemical symbol. It is a metal, and one of the alkali earth metals which are the elements in Group 2 of the periodic table. It is reactive, and as such is not found free in nature, but always appears in compounds with other elements. Wikipedia has additional information, and a link is provided.

What kind of pure substance is calcium or carbon?
Calcium is an example of a pure substance known as an element, specifically a metal. Carbon is also a pure substance, but it is an element that belongs to the non-metal group.
What is pure sample of calcium?
A pure sample of calcium is a silver-white metal that is highly reactive and not typically found in its elemental form in nature. It is commonly found in compound form, such as calcium carbonate in rocks like limestone, or in calcium phosphate in bones and teeth.
Why is calcium carbonate a pure substance but not an element?
Calcium carbonate is a pure substance because it has a fixed composition of calcium and carbonate ions. However, it is not an element because it is a compound made up of multiple elements (calcium, carbon, and oxygen) chemically bonded together.
