The Gold Foil Experiment (Ernest Rutherford)
Rutherford’s experiment would prove Nagaoka correct, and reinvent the model of the atom.
Ernest Rutherford's Gold Foil Experiment - Prezi
Rutherford was forced to discard the Plum Pudding model and reasoned that the only way the alpha particles could be deflected backwards was if most of the mass in an atom was concentrated in a nucleus.
A scientist called Ernest Rutherford designed an experiment to test the plum pudding model. It was carried out by his assistants Hans Geiger and Ernest Marsden.

Thompson's plum pudding model.
There was a complete paradigm shift; the atom was no longer seen as a mass positively charged matter with a few scattered electrons; now the model of the atom was a small, dense, positively charged nucleus surrounded by mostly empty space, with electrons traveling around the nucleus.
The results of Rutherford's experiments are still valid, but now we know that the nucleus is also composed of neutrons, thanks to James Chadwick (1932), and not just protons.
Also, it motivated other scientists to study the atom more intricately.
