ScienceChemistry
Quick Answer
Ernest Rutherford proposed the nuclear model of the atom in 1911. He showed that atoms are mostly empty space with a small dense nucleus.
The Full Story
Ernest Rutherford developed the nuclear model of the atom after the gold foil experiment, which he carried out with Hans Geiger and Ernest Marsden. In 1911, he concluded that most of an atom’s mass and positive charge must be concentrated in a tiny nucleus. This overturned the earlier “plum pudding” model of the atom. Rutherford later became known as the father of nuclear physics.
