There are two sublevels in the 2nd principal energy level. They are the 2s and 2p sublevels.
In the second principal energy level, there are two types of sublevels: the s sublevel and the p sublevel. The s sublevel can contain a maximum of 2 electrons, while the p sublevel can hold up to 6 electrons.

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

There are 2 sublevels in energy level 2: the s sublevel and the p sublevel.

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.

In the ground state, a sodium atom in the second principal energy level has two sublevels completely occupied: the 2s and the 2p sublevels. The 2s sublevel can hold a maximum of 2 electrons, and the 2p sublevel can hold a maximum of 6 electrons.

The second energy level can hold a maximum of 8 electrons. This level consists of two sublevels - the s sublevel can hold a maximum of 2 electrons, and the p sublevel can hold a maximum of 6 electrons.
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
