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.
