James Chadwick is best known for his discovery of the neutron in 1932. Prior to Chadwick's work, the understanding of atomic structure primarily included protons and electrons.
### Discovery of Neutrons
- **Neutrons**: Chadwick's experiments involved bombarding beryllium with alpha particles, which led to the emission of a new type of radiation that could not be explained by the presence of protons and electrons alone. He identified this radiation as being made up of neutral particles, which he termed "neutrons." This discovery provided a key understanding of atomic structure, leading to significant advancements in nuclear physics and the development of atomic energy.
### Protons and Electrons
- **Protons**: Discovered earlier by Ernest Rutherford in 1919, protons are positively charged particles found in the nucleus of an atom.
- **Electrons**: Discovered by J.J. Thomson in 1897, electrons are negatively charged particles that orbit the nucleus of an atom.
Chadwick's discovery of neutrons completed the fundamental understanding of atomic particles, as atoms are now understood to be composed of protons, neutrons, and electrons.
