Planetary Model - The model was proposed by physicist Niels Bohr in 1913. In this model, the electrons travel around the nucleus of an atom in distinct circular orbits, or shells.
Principal Quantum Number - This number describes the energy
level of an electron inside an atom.
Magnetic Quantum Number - This number describes the orbital within a sublevel.
Electron Spin - direction of the intrinsic quantum “spinning” of the electron
Angular momentum Quantum Number - This number describes the shape of the sublevel within an energy level.
