How does calcium atomic radius compare to magnesiums radius and potassium's radius?

Calcium has a larger atomic radius than magnesium because it is located further down in the periodic table, resulting in an increased number of electron shells. However, potassium, being in the same group as calcium but further down, has a larger atomic radius than both calcium and magnesium. Thus, the order of atomic radii from smallest to largest is magnesium, calcium, and then potassium.
