Question

what led to the discovery of the third subatomic particle the neutron​

Answer 1

Explanation:

The essential nature of the atomic nucleus was established with the discovery of the neutron by James Chadwick in 1932 and the determination that it was a new elementary particle, distinct from the proton. The discovery of fission led to the creation of both nuclear power and weapons by the end of World War II.

Answer 2

Answer:

❇ In 1932, James Chadwick tried similar experiments himself, and became convinced that the radiation ejected by the beryllium was in fact a neutral particle about the mass of a proton. ... Scientists soon realized that the newly discovered neutron, as an uncharged but fairly massive particle, could be used to probe other nuclei.
