Rutherford's Gold Foil - ChemEd DL

Ernest Rutherford, Hans Geiger and Ernest Marsden carried out their Gold Foil Experiment to observe the effect of alpha particles on matter. Rutherford devised a way to record the location of the alpha particles by surrounding the bombarded object with a sheet coated in ZnS, which would emit of flash of light when hit with an alpha particle.

Rutherford then used thicker aluminum foil (0.0005 cm thick) to block the radiation from the uranium. Adding four layers of the aluminum foil blocked much of the radiation, as shown in Fig. 3. However, after the fourth layer, it took another eight layers of aluminum to decrease the leak rate from 9.4 to 7.

In 1909 Rutherford disproved Sir J.J. Thomson's model of the atom as a uniformly distributed substance. Because only very few of the alpha particles in his beam were scattered by large angles after striking the gold foil while most passed completely through, Rutherford knew that the gold atom's mass must be concentrated in a tiny dense nucleus.

Rutherfords associates bombarded a very thin (##10^(-7)## m) gold foil with -particles.
