Explanation:

How did Chadwick prove the existence of neutrons?

To prove that the particle was indeed the neutron, Chadwick measured its mass. He could not weigh it directly. Instead he measured everything else in the collision and used that information to calculate the mass. For his mass measurement, Chadwick bombarded boron with alpha particles.
