SCIENTIFIC CONTRIBUTIONS 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.

Atomic theory can be used to answers the questions presented above. A pure gold necklace is made up of atoms.. In 1933, James Chadwick (1891-1974) discovered a new type of radiation that consisted of neutral particles. It was discovered that these neutral atoms come from the nucleus of the atom. This last discovery completed the atomic model.

Sir James Chadwick, CH, FRS (20 October 1891 - 24 July 1974) was an English physicist who was awarded the 1935 Nobel Prize in Physics for his discovery of the neutron in 1932. In 1941, he wrote the final draft of the MAUD Report, which inspired the U.S. government to begin serious atom bomb research efforts.

His favorite subjects were mathematics and physics. Aged 16, he won a scholarship to the Victoria University of Manchester. He had intended studying mathematics, but was interviewed by a physicist who assumed he wanted to study physics. Chadwick was too shy to contradict him, so he ended up enrolling as a physics major!

From 1957 to 1962 he was a parttime member of the United Kingdom Atomic Energy Authority. Chadwick has had many papers published on the topic of radioactivity and connected problems and, with Lord Rutherford and C. D. Ellis, he is co-author of the book Radiations from Radioactive substances (1930). Sir James was knighted in 1945.
