The range of the levels is between 0 to n-1. 3 minus 1 equals to 2, so we have 0, 1, 2 as sub levels. They are the same number of sub-levels.

2+2+6+2+6=18
(1s2,2s2,2p6,3s2,sp6) Sorry,I can't do exponents...
3 rd energy level has 3s 3p and 3d. 3p can be further subdivided into 3px, 3py and 3pz. 3d can be further subdivided into 3dxy, 3dxz, 3dyz, 3d(x2-y2) and 3dz2.
There are three subshells in the third energy level of an atom, namely 3s 3p and 3d.
When n=3 (principal energy level) you have 1 s sublevel, 3 p sublevels, and 5 d sublevels for a total of 9 sublevels.
Theoretically infinite.

There are two sublevels in the 2nd principal energy level. They are the 2s and 2p sublevels.
There are 2 energy sublevels in the second principal.

There are five sublevels in the fifth energy level: 5s, 5p, 5d, 5f, and 5g.

2 the s and p sublevels
There are 8 sublevels, or types of orbitals in the 8th energy level. They would be s, p, d,f, g, h, i,j.

The 2s and 2p sublevels in the second principal energy level are completely occupied in the ground state of a sodium atom.
1st energy has 1 sublevel -- 1 orbital -- 2 electrons 2nd energy level has 2 sublevels -- 4 orbitals -- 8 e- 3rd energy level has 3 sublevels -- 9 orbitals -- 18 e- 4th energy level has 4 sublevels -- 16 orbitals -- 32 e- Notice the pattern? number of orbitals = energy level squared Number of electrons = 2x number of orbitals
