Which of the following statements about this experiment is not correct?
The ultra-thin foil ensures that we can assume an alpha particle is scattered only once as it passes through.
The small fraction of alpha particles deflected by more than 90∘90^\circ90∘ indicates that the positive charge and mass of an atom are concentrated in a very small region.
The primary cause of the large-angle deflections is the electrostatic attraction between the positively charged alpha particles and the negatively charged atomic electrons.
The majority of the alpha particles pass through the foil with negligible deflection, showing that the atom consists mostly of empty space.
