Solution of the Schrödinger wave equation for the hydrogen atom results in a set of functions (orbitals) that describe the behavior of the electron. Each function is characterized by 3 quantum numbers: n, l, and ml. If the value of n = 3 ... The quantum number l can have values from to . ... The total number of orbitals possible at the n = 3 energy level is . If the value of l = 3 ... The quantum number ml can have values from to . ... The total number of orbitals possible at the l = 3 sublevel is
