Detailed Solution

The correct statements regarding Rutherford’s experiment are mass and positive charge of an atom is present inside the nucleus. Most of the space in an atom is empty.
Rutherford conducted the alpha particle scattering experiment. In the experiment, he observed that a very tiny fraction of alpha particles rebounded by 180 degrees which shows that the atom has a small positively charged centre, which he eventually named the nucleus. In the experiment, he also observed that the majority of the alpha particles went straight through the thin metal foil. From this observation, he concluded that most of the space in an atom is empty.
