What are the types of sub-levels?

Answer 1

If the principle energy level is n=1 then the type of sublevel is 1s

N=2---> type of sublevel is 2s and 2p

N=3---> type of sublevel is 3s, 3p, and 3d

N=4---> type of sublevel is 4s, 4p, 4d, and 4f

N=5---> type of sublevel is 5s, 5p, 5d, 5f and 5g

N=6---> type of sublevel is 6s, 6p, 6d, 6f, 6g, and 6h

N=7---> type of sublevel is 7s, 7p, 7d, 7f, 7g, 7h, and 7i

Note that:

s = 1 orbital

p = 3 orbitals

d = 5 orbitals

f = 7 orbitals

g = 9 orbitals

h = 11 orbitals

If you look closely its just adding 2 to each orbital. If you want to know the number of electrons occupying the orbitals just multiply the orbital by 2.
