Solution

True.

James Chadwick is indeed known for his work in isolating the neutron, a neutral particle that was first proposed by Ernest Rutherford. Although Rutherford's earlier work included the discovery of the nucleus and the nuclear model of the atom, he hypothesized the existence of a neutral particle to account for the mass of the atom that was unaccounted for by protons alone.

In 1932, Chadwick conducted experiments that led to the discovery of the neutron. He bombarded beryllium with alpha particles, which resulted in the emission of what was later identified as neutrons. This pivotal discovery not only confirmed Rutherford's hypothesis but also advanced the field of nuclear physics significantly, influencing the development of nuclear energy and technology. Thus, Chadwick's work can be seen as a crucial validation of Rutherford's initial proposal about the existence of a neutral particle in the atomic structure.
