Question

Faça a distribuição eletrônica dos elementos: CS (Z=55); Ga (Z=31); S (Z=16); Po (z=84)

Answer 1

Cs Z = 55: 
$1s^{2} 2s^{2}2p^{6}3s^{2}3p^{6}4s^{2}3d^{10}4p^{6}5s^{2}4d^{10}5p^{6}4f^{1}$

Ga Z = 31
$1s^{2} 2s^{2}2p^{6}3s^{2}3p^{6}4s^{2}3d^{10}4p^{1}$

S Z = 16
$1s^{2} 2s^{2}2p^{6}3s^{2}3p^{4}}$

Po Z = 84
$1s^{2} 2s^{2}2p^{6}3s^{2}3p^{6}4s^{2}3d^{10}4p^{6}5s^{2}4d^{10}5p^{6}4f^{14}$$5d^{10} 6p^{4}$
