Quick Answer
Ernest Rutherford is credited with discovering the nuclear structure of the atom in 1911. He showed that atoms have a tiny, dense nucleus.
The Full Story
Ernest Rutherford's gold foil experiment, carried out by Hans Geiger and Ernest Marsden, revealed that most alpha particles passed through gold foil while a few were sharply deflected. Rutherford concluded in 1911 that the atom must have a small, dense, positively charged nucleus. This replaced the earlier 'plum pudding' model. His model became a major step toward modern atomic physics.
