Solution

Q.
The correct increasing order of the ionic radii is [2023]

1 ${Ca}^{2 +} < K^{+} < {Cl}^{-} < S^{2 -}$

2 $S^{2 -} < {Cl}^{-} < {Ca}^{2 +} < K^{+}$

3 $K^{+} < S^{2 -} < {Ca}^{2 +} < {Cl}^{-}$

4 ${Cl}^{-} < {Ca}^{2 +} < K^{+} < S^{2 -}$

Ans.
(1)

The correct increasing order of size is ${Ca}^{2 +} < K^{+} < {Cl}^{-} < S^{2 -}$
