WebRutherford found that a small percentage of alpha particles were deflected at large angles, which could be explained by an atom with a very small, dense, positively-charged nucleus at its center (bottom). According to the accepted atomic model, in which an atom’s mass and charge are uniformly distributed throughout the atom, the scientists ... WebSep 20, 2024 · Rutherford's atomic model became known as the nuclear model. In the nuclear atom, the protons and neutrons, which comprise nearly all of the mass of the atom, are located in the nucleus at the center of the atom. The electrons are distributed around the nucleus and occupy most of the volume of the atom.

WebAccording to the Rutherford atomic model: The positive charge and most of the mass of an atom is concentrated in an extremely small volume. He called this region of the atom as … WebThe experiment proved that the Plum- Pudding Model was incorrect. Rutherford thought that all of the alpha particles would pass through the gold foil with little being repelled. He determined that most of the alpha particles passed through but there were many that were repelled at an angle or just bounced off. This helped him see that Thompson description … maipet reggio calabria
