Understanding the Rutherford Model
In this Rutherford model worksheet, students read about Rutherford's experiment with gold foil and alpha particles which led to the discovery of subatomic particles. Students answer six analysis questions about the experiment and...
PhET
Rutherford Scattering
Rutherford performed his famous experiment in 1907 with Marsden, showing the true atomic structure. This interactive simulation compares Rutherford's historical experiment to the Plum pudding model of the atom. In both models, alpha...
