(Z/e-)is in the order S -2> Cl -> K +> Ca +2

Q. The correct decreasing order of ionic size among the following species is $K^{+}, C l^{-}, S^{- 2}$ and $C a^{+ 2}$

$C a^{+ 2} > K^{+} > C l^{-} > S^{- 2}$

$K^{+} > C a^{+ 2} > C l^{-} > S^{- 2}$

$S^{- 2} > C l^{-} > K^{+} > C a^{+ 2}$

$S^{- 2} > C l^{-} > C a^{+ 2} > K^{+}$

$\frac{Z}{e ^{-}}$ is in the order $S^{- 2} > C l^{-} > K^{+} > C a^{+ 2}$

Q. The correct decreasing order of ionic size among the following species is K+,Cl−,S−2 and Ca+2

Ca+2>K+>Cl−>S−2

K+>Ca+2>Cl−>S−2

S−2>Cl−>K+>Ca+2

S−2>Cl−>Ca+2>K+
