Hint: For his 1932 discovery of the neutron, Chadwick is best known. A neutron is a particle with no electric charge that makes up the nucleus of an atom, along with positively charged protons. The findings of Chadwick were central to the discovery of nuclear fission, and eventually the development of the atomic bomb.
Complete answer:
1.He found the Neutron in atoms; James Chadwick played a vital role in atomic theory. The neutron is located in the centre of an atom, along with the protons in the nucleus.
2.They have neither a positive nor a negative charge, but they add the same effect as a proton to the atomic weight.
3.By using a neutron chamber in his experiments, Chadwick discovered this subatomic particle.
4.The task of tracking down evidence of the tightly bound "proton-electron pair" or neutron of Rutherford was assigned to James Chadwick.
5.It was found in 1930 that Beryllium emitted a very energetic stream of radiation when bombarded by alpha particles. He was awarded the Nobel Prize for his discovery in 1935.
Note:
Neutron bombarding elements can succeed in penetrating and splitting nuclei, producing a huge amount of energy. Please visit the Nobel Prize website for more on Chadwick's scientific contributions. Chadwick was a member of the British MAUD Committee, which concluded that it was possible and even inevitable to create nuclear arms. Such an assumption contributed to the decision of President Roosevelt to build the atomic bomb. In addition, in the Tube Alloy Project, Chadwick was an integral figure, the codename for the British programmed to design and develop nuclear weapons.
