Vedclass · Answer

(A) The ionization potential $(I.P.)$ is the energy required to remove the most loosely bound electron from an isolated gaseous atom.Among the given elements,Lithium $(Li)$ is an alkali metal with a large atomic size and low effective nuclear charge,making it easiest to remove its valence electron.The $I.P.$ values are approximately: $Li \approx 5.4 \ eV$,$He \approx 24.6 \ eV$,$N \approx 14.5 \ eV$,and $Zn \approx 9.4 \ eV$.Therefore,$Li$ has the least ionization potential.

$I.P.$ \text{ Trend}	Reason
$A$. $N > O$	Half-filled configuration
$B$. $Zr < Hf$	Lanthanide contraction
$C$. $Na > K$	$Z_{eff}$
$D$. $Al < Ga$	Transition contraction

Element	$A, B, C$
$IE_1$	$400, 550, 1150$
$IE_2$	$2650, 1070, 2090$
