Neutron was discovered by: _________?
Correct answer: A. Chadwick
- A. Chadwick
- B. Rutherford
- C. Neil Bohr
- D. Einstein
Explanation
James Chadwick discovered the neutron in 1932 by showing that penetrating radiation from beryllium consisted of neutral particles with nearly the mass of protons. Rutherford proposed the nuclear model and investigated the proton, but did not discover the neutron. The likely mistake is choosing Rutherford because of his major role in discovering the atomic nucleus.

About Composition of Atomic Nuclei
Atomic nuclei contain positively charged protons and electrically neutral neutrons, collectively called nucleons. Questions use atomic number, mass number and nuclear notation to identify isotopes, isobars and isotones, and may connect nuclear composition with nuclear charge, mass defect, binding energy and the stability of the nucleus.
