      Effective nuclear Charge of elements increases across a period and decreases down the group. Atomic radius. It is half of the distance between the two nuclei of two adjacent atoms in a metal or a diatomic molecule. Atomic radius decreases across a period because of the increase in effective nuclear charge on the valence electrons.
