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.

When Rutherford shot alpha particles through the gold foil, he hypothesized that the alpha particle will go through. However, he noticed that while most of the particles passed through, some were greatly deflected.
