what is the contribution of james chadwick to our understanding of atomic structure?​

Answer 1

Answer:

Chadwick is best known for his discovery of the neutron in 1932. A neutron is a particle with no electric charge that, along with positively charged protons, makes up an atom's nucleus. Bombarding elements with neutrons can succeed in penetrating and splitting nuclei, generating an enormous amount of energy.

Answer 2

Sir James Chadwick (1891-1974) was an English physicist and winner of the 1935 Nobel Prize in Physics.

James Chadwick began his academic studies at the University of Manchester under the tutelage of Ernest Rutherford. Here, he earned his B.S. in 1911 and his MSc in 1913. Chadwick then decided to take up research under Hans Geiger in Berlin. His intention was to study beta radiation, but shortly into this endeavor, World War I broke out and the German government imprisoned Chadwick in the Ruhleben internment camp for four years.

Aided by sympathetic German soldiers, Chadwick was able construct experiments even while imprisoned during the war. When the war came to a close, Chadwick returned to England and continued research under his previous advisor Ernest Rutherford at the Cavendish Laboratory at Cambridge University. There, he received his doctorate in 1921 and remained with the laboratory until he moved to the University of Liverpool in 1935.
