The principal quantum number is an integer n that corresponds to the gross energy states of the atom. Quantum numbers and atomic orbitals by solving the schrodinger equation hy ey, we obtain a set of mathematical equations, called wave functions y, which describe the probability of finding electrons at certain energy levels within an atom. Quantum mechanical calculations tell us that in 2s orbital there is a higher probability of finding electrons further out from the nucleus than the 1s orbital, so we might well predict that it takes less energy to remove an electron from a 2s orbital found in li than from a 1s orbital found in h.
