An electron in an atom is described by four quantum numbers:
The principal quantum number is a positive integer: 1, 2, 3, etc.
The azimuthal quantum number is a non-zero integer: 0, 1, 2, 3, etc.
The relationship between n and l is that l must always be strictly less than n. So, for n=1, the only permissible l value is 0. For n=2, l can be 0 or 1. So the number of types of orbitals per level is equal to n.
The relationship between l and ml is that ml is an integer between -l and +l. There are 2l+1 values of ml for any given value of l.
Since each n, l, ml triple specifies an orbital, if you work it out it turns out that there are n2 orbitals with a given principal quantum number n.
Each orbital can have two electrons (ms = +1/2 or -1/2), so there are twice that number of electrons.
The variable n here represents the Principal Quantum Number. This means the maximum number of electrons can be from 2 to 14 in naturally occurring materials
The number of sublevels is equal to n.

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.
relationship between the number of sides of afigure and the number of vertices
The number of protons is the atomic number.

The atomic number of a chemical element is identical to the number of protons.
The quantum number for that energy level.
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
The answar is: magnetic quantum number

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.
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.

For a neutral atom, the relationship between the number of protons and the number of neutrons is the same.
