Sir James Chadwick (20 October 1891 – 24 July 1974) was an English physicist who received the Nobel Prize in Physics in 1935 for his discovery of the neutron. In 1941, he wrote the final draft of the MAUD Report , which inspired the U.S. government to begin serious atom bomb research efforts.
James Chadwick at the 1933 Solvay Conference. Chadwick had discovered the neutron the year before while working at Cavendish Laboratory.. The discovery of the neutron and its properties was central to the extraordinary developments in atomic physics in the first half of the 20th century.

The neutron was discovered by James Chadwick at the Cavendish Laboratory at the University of Cambridge in February 1932. [1] [2] Two months later, his Cavendish colleagues John Cockcroft and Ernest Walton split lithium atoms with accelerated protons.
Atomic theory is the scientific theory that matter is composed of particles called atoms. The definition of the word "atom" has changed over the years in response to scientific discoveries. The definition of the word "atom" has changed over the years in response to scientific discoveries.
