The 2s and 2p sublevels in the second principal energy level are completely occupied in the ground state of a sodium atom.
Helium has two electrons which completely fills the first principal quantum level.
Increase in positive charge draws electrons closer to the nucleus. Increase in the number of occupied orbitals shields electrons in the highest occupied energy level from the attraction of proteins in the nucleus.

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.
filled energy sublevels
Zinc atoms contain 30 electrons in the electron configuration 1s22s22p63s23p63d104s2. There are a total of 7 sublevels that contain electrons in an atom of zinc in the ground state.
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
The 3p level
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 quantum number for that energy level.
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.
Sublevels
how would i know it is 2
The principal energy level is three, so there are three sublevels: 3s, 3p, and 3d. S,P and D
