Answer #1

Size of cation is always smaller than the parent atom.This is because when an electron is removed from the parent atom, positive charge of nucleus per electron will increase.As a result electrostatic force of attraction increases.Hence atomic size decreases.

So Na has a larger atomic radius than Na+.
