Magnetic Quantum Number

The magnetic quantum number, generally symbolized by m, denotes the orientation of the electron’s orbital with respect to the three axes in space.

Electron Spin

The Spin Quantum Number describes the behavior (direction of spin) of an electron within a magnetic field.

Possibilities for electron spin:

Pauli Exclusion Principle

Two electrons occupying the same orbital must have opposite spins

Exclusion Warning!

Assigning quantum numbers to electrons has been exluded and will not be tested!

Slide 18

Assigning the Numbers

The three quantum numbers (n, l, and m) are integers.

The principal quantum number (n) cannot be zero.

n must be 1, 2, 3, etc.

The angular momentum quantum number (l ) can be any integer between 0 and n - 1.

For n = 3, l can be either 0, 1, or 2.

The magnetic quantum number (ml) can be any integer between -l and +l.

For l = 2, m can be either -2, -1, 0, +1, +2.
