  • Dalton: Solid Sphere Model

    Dalton: Solid Sphere Model
    Dalton thought atoms were solid and hard spheres. He modeled them with wooden balls
  • Thomson: The Plum Pudding Model

    Thomson: The Plum Pudding Model
    Negative charged atoms were embedded with a positively charged area. Atom is mainly empty space with a positively charged nucleus.
  • Rutherford: The Nuclear Model

    Rutherford: The Nuclear Model
    Electrons were orbiting around a large nucleus in this model. Most was empty space and the nucleus occupied a small part relative to the rest of the atom
  • Bohr: The Bohr (Planetary) Model date

    Bohr: The Bohr (Planetary) Model date
    negatively charged atoms orbit a nucleus in the middle the orbits were not planar
  • Schrodinger: Quantum Mechanical Model

    Schrodinger: Quantum Mechanical Model
    Each orbit has an energy associated with it. Electrons occupy only certain orbits around the nucleus.
