Explanation:

Quantum Numbers

To completely describe an electron in an atom, four quantum numbers are needed: energy (n), angular momentum (ℓ), magnetic moment (mℓ), and spin (ms).The first quantum number describes the electron shell, or energy level, of an atom. ... The dynamics of any quantum system are described by a quantum Hamiltonian (H).
