Q98292


Solution:

  1. Ionic Radius : "Ca^{2+}<K^+<S^{2-}<P^{3-}"
  2. ionic Radius : "Al^{3+}<Na^+<F^-<N^{3-}"

As, number of electrons are the same in all ions, size difference occurs due to varying nuclear force of attraction. Greater the number of protons in the nucleus ("i.e." greater the atomic number), greater the nuclear binding force and thus smaller the ionic radius.
