Question

Faça a distribuição eletrônica em camadas dos átomos dos seguintes elementos
A- 26Fe2+
B- 26Fe3+
C- 12Mg2+
D- 9F-1

Answer 1

a)1s2-2s2-2p6-3s2-3p6-4s2-3d6 = Z- e= 26-2=24
k=2;l=8;m=8;n=6
b)1s2-2s2-2p6-3s3-3p6-4s2-3d6= Z- e= 26-3=23
k=2;l=8;m=8;n=5
c)1s2-2s2-2p6-3s2=Z-e=12-2=10(atomo neuto)
k=2;l=8
d)1s2-2s2-2p5=Z-e=9+1=10(atomo neutro)
k=2;l=8
