James Chadwick Atomic Theory - Sciencing
WEBNov 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.
James Chadwick - Wikipedia
WEBSir James Chadwick, CH, FRS (20 October 1891 – 24 July 1974) was an English physicist who was awarded the 1935 Nobel Prize in Physics for his discovery of the neutron in 1932. In 1941, he wrote the final draft of the MAUD Report, which inspired the U.S. government to begin serious atom bomb research efforts.
