Question

Consider the following ions

. The largest cation and largest anion are respectively}

• A. $Cs^{+}, S^{2-}$
• B. $Cs^{+}, P^{3-}$
• C. $Ba^{2+}, Cl^{-}$
• D. $K^{+}, P^{3-}$

Hint:

For isoelectronic ions: \[ \text{Radius} \propto \frac{1}{Z} \] Lower nuclear charge means larger ionic radius.
