Nov 27, 2018 · The Chadwick atomic theory arose from James Chadwick's discovery of the neutron. Scientists now know that the nucleus of the atom contains both positively charged protons and neutral neutrons, which have the same mass. Chadwick's discovery led directly to the development of the atomic bomb.

Chadwick's Atomic Model. Neutrons were found to have the same mass as protons which accounted for more of the mass of the atom and allowed the known mass of an atom and the known mass of its particles to match.
Its existence was first hypothesized by Rutherford in 1920, and later proved by James Chadwick in 1932. This ScienceStruck post explains how the discovery came about and the revolutionary impact it had on the understanding of the atomic structure.
