Indirect Measurement Predictions Ch. 1, Act. 6

Earnest Rutherford (1911) “The Gold Foil Experiment” Bombarded gold foil with  particles from the radioactive decay of uranium238. Most of the particles traveled through very thin gold foil without being deflected. Occasionally, particles would deflect, sometimes at angles > 90o. Results show that the dense positive charge is centrally located in the nucleus.

The Gold Foil Experiment Rutherford's Gold Foil Experiment wps.prenhall.com Note: The diameter of the atom was determined to be on the order of 100,000x larger than the nucleus!
