Options
- AElectron
- BProton
- CAtomic Nucleus
- DNeutron
Correct answer
C. Atomic Nucleus
Step-by-step solution
Rutherford's alpha-particle scattering experiment was responsible for the discovery of the Atomic Nucleus. Before Rutherford's experiment, people knew about Proton and Electron, however, the existence of neutrons was not known. Rutherford's alpha-particle scattering experiment that the Atomic nucleus existed. In the experiment, a fraction of the particles bounced back at an angle of 180^ providing that nearly all the mass of an atom is contained in the nucleus.
