Magnetic Quantum Number, m l The magnetic quantum number is an integer that specifies the orientation of the orbital –the direction in space the orbital is aligned relative to the other orbitals Values are integers from −l to +l –including zero –gives the number of orbitals of a particular shape »when l = 2, the values of m l are −2, −1, 0, +1, +2; which means there are five orbitals with l = 2 74 Tro: Chemistry: A Molecular Approach, 2/e
