Calcium's atomic weight of 40.078 rounds to a mass number of 40. Subtracting 20 from 40 yields a result of 20. This means an atom with 20 protons and 20 neutrons must be an atom of calcium. In some cases, calcium does not have 20 neutrons.
Calcium is the fifth-most-abundant element by mass in the human body, where it is an important cellular ionic messenger with many functions. Calcium also serves as a structural element in bone. It is the relatively high-atomic-number calcium in the skeleton that causes bone to be radio-opaque.
