  • Rutherford: The Nuclear Model

    A atom consists of a very small, positively charged nucleus surrounded by the negatively charged electrons.
  • Bohr: The Bohr (Planetary) Model

    Bohr: The Bohr (Planetary) Model

    the electrons encircle the nucleus of the atom in specific allowable paths called orbits.
  • Schrodinger: Quantum Mechanics Model
