What was proven to exist in an atom, by Rutherford's gold foil experiment?
Nucleus
Rutherford's gold foil experiment proved the existence of a dense, positively charged nucleus at the centre of the atom.
The electron, neutron and proton were established through other separate experiments, not this specific gold foil scattering experiment.
Hence, Nucleus is the correct answer.
The discovery of the atomic nucleus by bombarding a thin gold foil with alpha particles is associated with which of the following scientists?
