Ionii radious α change on Anion α (1/ text charge on Ation )

Q. The correct order of the decreasing ionic radii among the following isoelectronic species is

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

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

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

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

Ionii radious $α$ change on Anion
$α \frac{1}{charge on Ation}$

Q. The correct order of the decreasing ionic radii among the following isoelectronic species is

Ca2+>K+>S2−>Cl−

Cl−>S2−>Ca2+>K+

S2−>Cl−>K+>Ca2+

K+>Ca2+>Cl−>S2−

Ionii radious α change on Anion α charge on Ation 1​

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

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

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

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