$Ne$

Vedclass · Answer

(C) The ionization potential increases across a period from left to right due to an increase in effective nuclear charge and a decrease in atomic size. Among the given elements ($Li$,$B$,$F$,$Ne$),$Ne$ is a noble gas located at the end of the period. $Ne$ has a stable,fully-filled electronic configuration $(1s^2 2s^2 2p^6)$,which requires a very high amount of energy to remove an electron. Therefore,$Ne$ has the highest ionization potential.

Element	$IE_1$	$IE_2$	$IE_3$
$P$	$495.8$	$4562$	$6910$
$Q$	$737.7$	$1451$	$7733$
$R$	$577.5$	$1817$	$2745$
