James Chadwick discovered the neutron in 1932, an uncharged subatomic particle found in the atomic nucleus. This discovery played a crucial role in nuclear physics and the development of the atomic bomb. Key Points: 1. Neutrons have no electric charge and are slightly heavier than protons. 2. Their discovery advanced nuclear fission studies. 3. Neutrons are responsible for stabilizing the atomic nucleus. 4. Chadwick received the Nobel Prize in Physics in 1935 for this discovery. 5. His work contributed to the Manhattan Project during World War II. Bee Facts: • Thermal ionization (a): A method used in mass spectrometry. • Electron (b): Discovered by J.J. Thomson in 1897. • Wave theory of light (c): Propounded by Christian Huygens. • Neutron (d): Discovered by Chadwick in 1932.
