What is calcium's atomic radius?

Atomic Radius:

The atomic radius of an atom is half the distance between two nuclei that are next to each other. The size of atomic radii are measured in picometers (pm), where one picometer is one trillionth of a meter, or an angstrom (A). One angstrom is the same as 100 pm.
