When an atom donates all electrons fremantle its valency shell then positive attraction from nucleus increases so atom tends to come closer to nucleus so it is smaller than parent atom
When an atom gains electrons to valency shell then negative power of electrons in valency shell increases so attraction of nucleus on shells decreases and atom tends to expand or bulge
Na+ is smaller than Na
Cl- is larger than Cl
