Rutherford
Bohr
Newton
Answer is Right!
Answer is Wrong!
The correct answer is (a). James Chadwick discovered the neutron in 1932. He was a British physicist who was awarded the Nobel Prize in Physics in 1935 for his discovery.
Rutherford (b) is known for his gold foil experiment, which showed that atoms are mostly empty space. Bohr (c) is known for his model of the atom, which proposed that electrons orbit the nucleus in fixed orbits. Newton (d) is known for his laws of motion and universal gravitation.
Chadwick’s discovery of the neutron was a major breakthrough in physics. It helped to explain the structure of the atom and the nature of nuclear reactions.
