Introduction:
James Chadwick discovered the neutron in the year 1932. He used a new experimental technique to discover the neutron. He bombarded beryllium with alpha particles and observed the emission of neutral particles.
Explanation:
Chadwick knew that the particles emitted were not a pair of electron and proton or an atom because of the following reasons:
1. Mass of emitted particles:
The mass of the emitted particles was not equal to the mass of a proton or an electron. The mass of the emitted particles was slightly greater than the mass of a proton. Therefore, Chadwick concluded that the particles were not a pair of electron and proton.
2. No charge:
The emitted particles had no charge. If they were an atom, they would have had a charge because of the presence of electrons. Therefore, Chadwick concluded that the emitted particles were not an atom.
3. Penetration power:
The emitted particles had a very high penetration power. They could penetrate through thick layers of matter. This indicated that the particles were not charged because charged particles are easily deflected by matter.
4. Interaction with matter:
The emitted particles were able to interact with matter by knocking out protons from the nuclei of other atoms. This indicated that the particles were not photons because photons do not have mass and cannot interact with matter in this way.
Conclusion:
Based on these observations and reasoning, James Chadwick concluded that the particles emitted were a new sub-particle called the neutron.
