[1]
Alkali metals with one elctron in the outer most shell to be easily donated and become positive ion
[2]
Halogens with  p 5. it accepts an electron to become negatively charged halide
[3]

Inert gases- p orbital is completely filled
p 6 except for He  where s orbital  is completely filled s 2
[4]
p level orbitals fill in
from p 1 - p6
[5]
The transition series with the d level orbitals filled in from d1 - d10
[6]
Lanthanum to Lutesium have the f level orbital filling from 4f 1 - 4f14
[7]
Actinium to Lawrencium
5f 1 - 5f14
