The Effects of the Gold Foil on Alpha Particles

According to Thompson's model the positive material in the atom was too spread out to make much of a difference to interfere with anything and therefore he expected the particles to pass straight through the gold foil. There was astonishment however although well most of the particles did pass straight through as he as he had expected but to his astonishment some of them would have some of the alpha particles would have reflected right back at him. It just didn't make sense to him the alpha particles according to the current theory should have because of their kinetic energy and their size should be not affected by the tiny thin strip of gold foil. So on the basis of this discovery Rutherford proposed a new model of the atom you could
