Final answer:

Rutherford's gold foil experiment demonstrated the small, dense nucleus of the atom.


Explanation:

Ernest Rutherford's gold foil experiment provided direct evidence for the size and mass of the nucleus by scattering alpha particles from a thin gold foil. The experiment showed that the atom is composed of a small, dense nucleus with electrons occupying the mostly empty space around it, leading to the formulation of the Rutherford model of the atom.
