  • Dalton

    Dalton
    The Solid Sphere model- Dalton believed that the model of the atom was just a solid sphere.

  • JJ Thomson

    JJ Thomson
    Plum Pudding Model- Electrons were added to the model. He discovered that negatively charged electrons that were balanced out with a positively charged "cloud" around them. Found using the Cathode Ray Experiment.

  • Rutherford

    Rutherford
    Using the Gold Foil experiment, Rutherford found that an atom has a positively charged center (the nucleus).

  • Bohr

    Bohr
    Bohr created the atomic model where electrons orbit the nucleus.

  • Heisenberg/Schrodinger

    Heisenberg/Schrodinger
    This is the modern atomic model. They added the uncertainty principle and wave mechanics to the model.

  • Chadwick

    Chadwick
    Chadwick created a model that has neutrons in the nucleus.
