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

The second principle energy level is the energy level that comes after the first principle energy level. The second energy level is farther from the atomic nucleus and contains the 2s and 2p sublevels.
There are five sublevels in the fifth energy level: 5s, 5p, 5d, 5f, and 5g.

2 the s and p sublevels
The 2s and 2p sublevels in the second principal energy level are completely occupied in the ground state of a sodium atom.
The second principle energy level is the energy level that comes after the first principle energy level. The second energy level is farther from the atomic nucleus and contains the 2s and 2p sublevels.
the orbitals of the sublevels of the same principal energy level differ in shape which describes where the electron is likely to be found. Also the orbitals of sublevels have different energy levels. In ascending enegy in any level s < p < d < f < g etc HOWEVER whether the different sublevels exist depends on the principal energy level ie 1s 2s, 2p 3s, 3p, 3d 4s, 4p, 4d, 4f

By the first principle energy level I assume you are referring to the lowest atomic orbital or ta principal quantum number of 1. This orbital holds 1 pair of 2 electrons.
There are 8 sublevels, or types of orbitals in the 8th energy level. They would be s, p, d,f, g, h, i,j.
