Being isoelectronic species(same valence electrons). Therefore more the protons more is the force of attraction on electrons.Removing electrons does not change the atomic number. As we know that Ca=20 and K=19 therefore there cations also have same atomic number.Hence Ca+2 having more protons(no. of protons is same as atomic number) means more force which means a smaller radius of Ca+2 on comparison with K+1

According to the atomic number sequencly increases there atomic radius, atomic mass and valance electron on outer orbit ca+ have lower than k+
