wavefunction is described in Schrödinger's equation by three properties (later
Wolfgang Pauli added a fourth). The three properties were (1) an "orbital" designation, indicating whether the particle wave is one that is closer to the nucleus with less energy or one that is farther from the nucleus with more energy, (2) the shape of the orbital, i.e., an indication that orbitals were not just spherical but other shapes, and (3) the
magnetic moment of the orbital, which is a manifestation of force exerted by the charge of the electron as it rotates around the nucleus.
