(C) Rutherford's alpha-particle scattering experiment involved bombarding a thin gold foil with alpha particles. He observed that most of the alpha particles passed straight through the foil,but a small fraction were deflected at large angles,and some even bounced back. This led to the conclusion that the positive charge and most of the mass of the atom are concentrated in a very small,dense region at the center,which he named the atomic nucleus.

Rutherford's alpha-particle scattering experiment was responsible for the discovery of
