With an atomic number of 20, calcium (Ca) is the fifth most abundant element in Earth's crust. This common element is not an alkali metal, non-metal, or transition metal, but is instead classified into a specific group with distinct chemical properties. Understanding this classification is key to grasping its behavior in everything from human bones to industrial applications.

Over 99% of the body’s total calcium is found in the teeth and bones, making it the most abundant mineral in the human body. A short definition of calcium describes it as a vital mineral essential for skeletal health and numerous critical physiological processes, from nerve transmission to muscle function.

Calcium (Ca), a reactive metal with atomic number 20, is the most abundant metallic element in the human body and the fifth most abundant element in Earth's crust. As an essential element for life, understanding what group name calcium belongs to is fundamental to grasping its chemical behavior and its widespread importance in nature. It is officially classified as an alkaline earth metal.
