The principal quantum number, n, determines the energy level of an electron in an atom. For any energy level n, the total number of electrons it can hold is given by 2n^2. For n = 4, the calculation is 2(4)^2 = 2(16) = 32. Therefore, all of the orbitals with n = 4 can contain a total of 32 electrons.
