Periodicity in atomic properties

Question

Which has most stable +2 oxidation state

Moderate

A

$S n$
B

$P b$
C

$F e$
D

$A g$

Solution

$P b^{2 +} (5 d^{10} 6 s^{2})$ has the most stable +2 oxidation state because here the d-orbital is completely filled and is more stable than $F e^{2 +} (3 d^{6}) .$ Again $A g^{+} (4 d^{10})$ is more stable as here again the d-orbital is completely filled and $A g^{2 +}$ is not easily obtained. $P b^{2 +}$ is more stable compared to ${Sn}^{2 +} (4 d^{10} 5 s^{2})$
because of its large size.
