    Quantum numbers describe values of conserved quantities in the dynamics of the quantum system.Quantum numbers often describe specifically the energies of electrons in atoms, but other possibilities include angular momentum, spin etc.

    #The first, n, describes the electron shell, or energy level.

    #The second, ℓ, describes the subshell (0 = s orbital, 1 = p orbital, 2 = d orbital, 3 = f orbital, etc.).

    #The third, mℓ, describes the specific orbital (or "cloud") within that subshell.*

    #The fourth, ms, describes the spin of the electron within that orbital.
