- A \(\mathrm{Mg}^{2+}\)
- B \(\mathrm{S}^{2-}\)
- C \(\mathrm{Na}^{+}\)
- D \(\mathrm{Cl}^{-}\)
Answer & Solution
Correct Answer
(A) \(\mathrm{Mg}^{2+}\)
Step-by-step Solution
Detailed explanation
For isoelectronic set of ions, higher the charge on cation, it will be smaller and that on anion will be larger. The order of ionic radii will be
