who is the person mentioned above?
He is a British physicist.
James Chadwick
Sir James Chadwick, (20 October 1891 – 24 July 1974) was a British 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 atomic bomb research efforts. He was the head of the British team that worked on the Manhattan Project during World War II. He was knighted in Britain in 1945 for his achievements in physics.
who provided evidence to suggest the existence of the neutron James Chadwick. what is the above mentioned substance? It is a subatomic particle, symbol or , which has a neutral charge. what are its properties? It is dependent on both atomic and neutron numbers. what is its nature? The neutron has no measurable electric charge, it is influenced by magnetic fields. Its magnetic moment has a negative value, because its orientation is opposite to the neutron's spin.

James Chadwick [SEP] Introduction
He was Rutherford's assistant director of research at the Cavendish Laboratory for over a decade at a time when it was one of the world's foremost centres for the study of physics, attracting students like John Cockcroft, Norman Feather, and Mark Oliphant. Chadwick followed his discovery of the neutron by measuring its mass. He anticipated that neutrons would become a major weapon in the fight against cancer. Chadwick left the Cavendish Laboratory in 1935 to become a professor of physics at the University of Liverpool, where he overhauled an antiquated laboratory and, by installing a cyclotron, made it an important centre for the study of nuclear physics.
