Geiger–Marsden experiments - Wikipedia

WebBetween 1908 and 1913, Rutherford, Geiger, and Marsden ran a series of experiments where they pointed a beam of alpha particles at a thin foil of metal and, [7] using the scintillation method devised by Crookes, Elster, and Geitel, [8] [9] studied the scattering pattern of the alpha particles with the aid of a fluorescent screen. WebThomson finally proved atoms were made up of smaller components, something scientists had been puzzled by for a long time. Thomson called the particle “corpuscles”, not an electron. The name electron was suggested by George Francis Fitzgerald. Why was the discovery of the electron important? Web10 de abr. de 2024 · 21:10. Atoms and Molecules - Science - Class 9. Fun School.
