Name Symbol Value examples

Principal quantum number n n = 1, 2, 3, …

Azimuthal quantum number (angular momentum) ℓ for n = 3: ℓ = 0, 1, 2 (s, p, d)

Magnetic quantum number (projection of angular momentum) mℓ for ℓ = 2: mℓ = −2, −1, 0, 1, 2

Spin quantum number ms for an electron s = 12, so ms = −12, +12
