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 quantum number for that energy level.
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.
Principal energy levels are an atom's major energy levels, ranging in value from 1 to 7. Energy sublevels are contained within principal energy levels, and their number increases as the value of the principal energy level increases.

The 2s and 2p sublevels in the second principal energy level are completely occupied in the ground state of a sodium atom.
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.
2 the s and p sublevels

The principal energy level is three, so there are three sublevels: 3s, 3p, and 3d. S,P and D
