The Gold Foil Experiment helped with the discovery of the positively charged nucleus.
The Gold Foil Experiment
Concept #1: Rutherford Gold Foil Oil Experiment
Example #1: The gold foil Rutherford used in his experiment had a thickness of approximately 6.0 x 10-3 mm. If a single gold atom has a diameter of 2.9 x 10-8 cm, how many atoms thick was Rutherford’s foil?
Concept #2: Nuclear Model
The Gold Foil Experiment helped to disprove Thomson's Plum Pudding Model of the atom.
Example #2: Rutherford’s experiment with alpha particle scattering by gold foil established that:
