1 gen 1911 anni - Rutherford's Atomic Model

Descrizione:

Ernest Rutherford's gold foil experiment showed that most of the atom is empty space with a positive charge that is localized over a very tiny volume of the atom, which contains most of the atom's mass, known as the nucleus today. He shot a-particles through a sheet of gold, and to his surprise some of them bounced off of the sheet. His atomic model states that the atom has a tiny, dense, positively charged core called a nucleus, in which nearly all the mass is concentrated, around which the light, negative particles, called electrons, circulate at some distance.
