Question

In the P 3, S 2. and Cl- ions, the increasing order of size is (A) S 2 < Cl -< p 3 (B) Cl -< S 2< P 3- (C) S 2-< P 3-< Cl - (D) P 3-< S 2-< Cl -

In isoelectronic species, the size of ions decreases as nuclear charge or atomic weight increases. (Atomic weight of P =30, S =32 and Cl =35 ). Therefore Cl -< S 2< P 3

Q. In the $P^{3}, S^{2}$ . and $C l^{-}$ ions, the increasing order of size is

$S^{2} < C l^{-} < p^{3}$

$C l^{-} < S^{2} < P^{3 -}$

$S^{2 -} < P^{3 -} < C l^{-}$

$P^{3 -} < S^{2 -} < C l^{-}$

In isoelectronic species, the size of ions decreases as nuclear charge or atomic weight increases.

(Atomic weight of $P = 30, S = 32$ and $Cl = 35$ ).

Therefore $C l^{-} < S^{2} < P^{3}$

Q. In the P3,S2. and Cl− ions, the increasing order of size is

S2<Cl−<p3

Cl−<S2<P3−

S2−<P3−<Cl−

P3−<S2−<Cl−
