Rutherford overturned Thomson's model in 1911 with his well-known gold foil experiment in which he demonstrated that the atom has a tiny and heavy nucleus. Rutherford designed an experiment to use the alpha particles emitted by a radioactive element as probes to the unseen world of atomic structure. If Thomson was correct, the beam would go straight through the gold foil. Most of the beams went through the foil, but a few were deflected. Web7 apr. 2024 · According to Rutherford’s atomic model, the positively charged particles and most of the atom’s mass was concentrated in a minimal volume. He called this region of …
