    $2, 8, 18, 32$
  • D
    $2, 8, 10, 8$

Answer

Correct option: A.
$2, 8, 2, 2$
a
                                                          Max in last shell

$s=n s^{1-2}$                                                  $2$

$\mathrm{p}=\mathrm{ns}^{2} \mathrm{np}^{1-6}$                                           $8$

$\mathrm{d}=(\mathrm{n}-1) \mathrm{d}^{1-10} \mathrm{ns}^{0-2}$                         $2$

$\mathrm{f}=(\mathrm{n}-2) \mathrm{f}^{1-14}(\mathrm{n}-1) \mathrm{d}^{0-1} \mathrm{ns}^{2} $       $2$
