first modern concept of atomic structure; all of the positive charge and most of the mass of the atom are contained in a compact nucleus; a number of electrons (equal to the atomic number) occupy the rest of the volume of the atom and neutralize the positive charge

found that the collision of alpha particles with nitrogen atoms resulted in the disintegration of the nitrogen and the production of hydrogen nuclei (protons) and an isotope of oxygen. He was the first person to achieve artificial transmutation of an element. 5
