Vedclass · Answer

(B) The tendency to form a univalent gaseous cation is determined by the first ionization energy $(IE_1)$.Lower ionization energy corresponds to a higher tendency to form a cation.Comparing the given configurations:$A$: $1s^2 2s^2 2p^6 3s^2$ (Fully filled $s$-orbital,high $IE_1$)$B$: $1s^2 2s^2 2p^6 3s^2 3p^1$ (Valence electron in $3p$ orbital,lowest $IE_1$ among the options)$C$: $1s^2 2s^2 2p^6 3s^2 3p^2$ (Higher $IE_1$ than $B$ due to increased effective nuclear charge)$D$: $1s^2 2s^2 2p^6 3s^2 3p^3$ (Half-filled $p$-orbital,high $IE_1$)Therefore,the configuration $1s^2 2s^2 2p^6 3s^2 3p^1$ has the lowest ionization energy and the highest tendency to form a univalent cation.

List-$I$ (Electronic configuration of neutral atom where $n=2$)	List-$II$ ($1^{st}$ Ionization Energy in $\text{kJ mol}^{-1}$)
$A. ns^2$	$I. 2080$
$B. ns^2np^1$	$II. 899$
$C. ns^2np^3$	$III. 800$
$D. ns^2np^6$	$IV. 1402$

Which of the following electronic configurations will have the highest tendency to form a univalent gaseous cation?
