Ordem crescente de energia:

$\mathsf{ 1s^2~2s^2~2p^6~3s^2}$

$\mathsf{ 3p^6~4s^2~3d^{10}~4p^6}$

$\mathsf{ 5s^2~4d^{10}~5p^6~6s^2}$

$\mathsf{ 4f^{14}~5d^{10}~6p^6}$

$\mathsf{7s^2~5f^{14}~6d^{10} }$

$\mathsf{7p^6 }$

Portanto:

$\mathsf{a)~ 1s^2~ 2s^1 =3}$

$\mathsf{b)~ 1s^2~2s^2~ 2p^6~ 3s^2~3p^6~4s^2=20 }$

$\mathsf{c)~ 1s^2~2s^2~2p^6~3s^2~3p^5=17 }$
