In Rutherford's famous experiment, he shot heavy, fast moving, positive alpha particles at a thin gold foil. Since the intact atom had no net charge and the electron and proton had opposite charges, the next step after the discovery of subatomic particles was to figure out how these particles were arranged in the atom. What are the four basic functions of a computer system? Neutrons generally result from nuclear reactions, such as nuclear fission (as in nuclear reactors and fission-based nuclear weapons) and charged-particle activation of target atoms (as with some accelerator-produced radioisotopes). These are the reflected rays. Explain why you expect the particles to take these paths. However, it did not completely address the nature of the electrons and the way in which they occupied the vast space around the nucleus. How does Rutherford's model of the atom explain why some of the alpha particles directed at the gold foil were deflected straight back toward the source? Rutherford's finding advanced the model of the atom from the plum pudding model in which the atom was a sphere of positive charge with electrons scattered throughout to the first nuclear model. They found that most alpha particles were not deflected at all, and a few were deflected at very large angles.
