Answer:

James Chadwick

Explanation:

In his first experiment, Rutherford was unable to predict the total mass of nucleus. He noticed that if only electrons and protons are present in the nucleus then by adding their masses, it falls short of the net mass of the atom. so he concluded that there must be another particle and that Particle was later discovered by James Chadwick in 1932.
