Webrealized that the plum-pudding model of the atom did not explain his results. In 1911, he revised the atomic theory and developed a new model of the atom, as shown in Figure 6. To explain the deflection of the particles, Rutherford proposed that in the center of the atom is a tiny, extremely dense, positively charged region called the nucleus .Most of the atom’s … WebThe Geiger–Marsden experiments (also called the Rutherford gold foil experiment) were a landmark series of experiments by which scientists learned that every atom has a nucleus where all of its positive charge and most of its mass is concentrated. They deduced this after measuring how an alpha particle beam is scattered when it strikes a thin metal foil.
