Question
Outermost electronic configurations of four elements $A, B, C, D$ are given below.
$3 s^{2}$; $3 s^{2} 3 p^{1}$; $3 s ^{2} 3 p ^{3}$; $3 s^{2} 3 p^{4}$
The correct order of first ionization enthalpy for them is.
$3 s^{2}$; $3 s^{2} 3 p^{1}$; $3 s ^{2} 3 p ^{3}$; $3 s^{2} 3 p^{4}$
The correct order of first ionization enthalpy for them is.
$3 s ^{2} 3 p ^{1} \rightarrow Al$
$3 s ^{2} 3 p ^{3} \rightarrow P$
$3 s ^{2} 3 p ^{4} \rightarrow S$
$C > D > A > B$
