Vedclass · Accepted Answer

$1s^2 2s^2 2p^6 3s^1$

Vedclass · Answer

(C) The second ionization energy is the energy required to remove the second electron from a unipositive ion. For the configuration $1s^2 2s^2 2p^6 3s^1$,removing the first electron results in a stable noble gas configuration $(1s^2 2s^2 2p^6)$. Removing the second electron from this stable octet configuration requires a very high amount of energy. Therefore,the element with the configuration $1s^2 2s^2 2p^6 3s^1$ will have the highest second ionization energy.

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