$Li$

Vedclass · Answer

(C) The ionization potential $(I.P.)$ generally decreases down a group and increases across a period. $Li$ (Lithium) belongs to Group $1$ (Alkali metals) and has a valence electronic configuration of $2s^1$. Due to its large atomic size and the presence of a single electron in the outermost shell,it is very easy to remove the valence electron. Comparing the given elements: $He$ (Noble gas,very high $I.P.$),$H$ (Non-metal,high $I.P.$),$Fe$ (Transition metal),and $Li$ (Alkali metal). $Li$ has the lowest ionization potential among the given options.

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