Vedclass · Answer

(D) $Ag$ has the electronic configuration $[Kr] \, 4d^{10} \, 5s^1$,making $+1$ its stable oxidation state.$Fe^{3+}$ is more stable than $Fe^{2+}$ due to the half-filled $3d^5$ electronic configuration.$Sn^{2+}$ is less stable than $Sn^{4+}$ because the $+4$ oxidation state is more stable for tin.In $p$-block elements,the inert pair effect makes the lower oxidation state more stable as we move down the group. Thus,$Pb^{2+}$ is more stable than $Pb^{4+}$ due to the inert pair effect.

The element exhibiting the most stable $+2$ oxidation state among the following is
