Explanation:
because upon losing 1 electron it acquires a positive charge as the number of protons get more than the number of electrons .due to this the nuclear charge increases and the electrons in the outermost shell are attracted towards the nucleus with a greater force due to which the size decrease . hence radius of Na+ cation is less than Na atom
