Some consider the 'p' block to be 'B' sub groups and some others consider it to be 'A' sub groups
some authors call them as group 12 to 18 as well, I have used from IIIB to VIII B.
[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
