WebAug 10, 2024 · The nucleus is the tiny, dense, central core of the atom and is composed of protons and neutrons. 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. WebErnest Rutherford imagined the atom as a tiny solar system, with electrons orbiting a large nucleus and essentially space The nucleus filled just a tiny fraction of the atom When Rutherford suggested his model, which featured a nucleus made up entirely of protons, the neutron had not yet been identified Nuclear Model of An Atom

At Cambridge, Rutherford started to work with J. J. Thomson on the conductive effects of X-rays on gases, work which led to the discovery of the electron which Thomson presented to the world in 1897. Hearing of Becquerel's experience with uranium, Rutherford started to explore its radioactivity, discovering two types that differed from X-rays in their penetrating power.

Scattering from a Rutherford atom Evidently a head-on collision with the heavy nucleus of a Rutherford atom could drastically alter the path of the much lighter alpha particle. Conversely, much of the atomic volume was now assumed to contain only the very light electrons, which could not produce much deflection.
