Na+ is smaller than Na because Na+ is formed when an electron is lost from the Na atom,Thus the effective nuclear charge increases bcz the number of protons exceeds the number of electrons .This results in bringing the valence shell a little closer to the nucleus because of a very strong nuclear pull.
