Ernest Rutherford (E. Rutherford) is widely regarded as the “Father of Nuclear Physics”. His experiments, particularly the gold foil experiment, led to the discovery of the atomic nucleus and the idea that the atom is mostly empty space. He also coined the terms “alpha” and “beta” rays, discovered the proton, and performed the first artificial nuclear transmutation.

Rutherford’s work revolutionized the understanding of atomic structure and radioactivity.
J.J. Thomson discovered the electron.
Niels Bohr developed an early model of the atom based on quantum mechanics.
James Chadwick discovered the neutron.

Rutherford received the Nobel Prize in Chemistry in 1908 for his investigations into the disintegration of the elements, and the chemistry of radioactive substances.
