In the Rutherford scattering experiment, a beam of alpha particles was fired at a thin gold film with some of the particles being considerably deflected. This shows that
a gold nucleus contains protons, neutrons and electrons uniformly distributed in a tiny volume
the gold nucleus is positively charged and is concentrated in a tiny volume
the gold nucleus emitted alpha particles
the gold nucleus is concentrated in a tiny volume and contains alpha particles
