Which of the following scientists discovered neutrons and was awarded the Nobel Prize for it?

Options :
  1. Rutherford
  2. Chadwick
  3. Bohr
  4. Goldstein
Answer and Explanation :-

Answer: Option 2


Sir James Chadwick was an English physicist who was awarded the 1935 Nobel Prize in physics for his discovery of the neutron in 1932. He was the head of the British scientists who worked on the Manhattan Project during World War II. He was knighted in England in 1945 for achievements in physics. In 1932, James Chadwick performed a series of experiments at the University of Cambridge, showing that the gamma ray hypothesis was untenable. He suggested that the new radiation consisted of uncharged particles of approximately the mass of the proton, and he performed a series of experiments verifying his suggestion. These uncharged particles were called neutrons, apparently from the Latin root for neutral and the Greek ending -on (by imitation of electron and proton).
