Vedclass · Answer

(B) Let us analyze the statements:$A$. The second ionization energy of $S$ $(3s^2 3p^4)$ is higher than $Cl$ $(3s^2 3p^5)$ because after removing one electron,$S^+$ achieves a stable half-filled $p^3$ configuration.$B$. The third ionization energy of $P$ $(3s^2 3p^3)$ is actually lower than that of $Al$ $(3s^2 3p^1)$ because $Al^{2+}$ has a stable noble gas core configuration $([Ne] 3s^1)$,making the removal of the third electron very difficult. Thus,this statement is incorrect.$C$. The first ionization energy of $Al$ and $Ga$ are similar due to the poor shielding effect of $d$-electrons in $Ga$ (lanthanoid contraction effect).$D$. The second ionization energy of $B$ $(2s^2 2p^1)$ is greater than $C$ $(2s^2 2p^2)$ because the second electron in $B$ is removed from the stable $2s^2$ orbital.
