AJ.J. Thomson
BRutherford
CPriestly
DChadwick
Answer:
D. Chadwick
Read Explanation:
The neutron was discovered by James Chadwick in 1932.
James Chadwick:
James Chadwick was a British physicist who made the discovery while working at the Cavendish Laboratory at Cambridge University.
Experiment:
Chadwick's discovery was based on an experiment where he bombarded beryllium with alpha particles, resulting in the emission of neutral radiation. He demonstrated that this radiation consisted of particles with a mass similar to that of protons but with no charge.
Conclusion:
Chadwick's discovery of the neutron revolutionized the field of nuclear physics and led to a deeper understanding of the atomic nucleus.
