Some statements about the Rutherford’s a-particle scattering experiment are given : I. As most of the a-particles passed through the gold foil without getting deflected, the positive charge of the atom occupies the entire space.
II. As very few particles were deflected from their path, very little space inside the atom is empty.
III. As a very small fraction of a-particles were deflected by 180°, all the positive charge and mass of the gold atom were concentrated in a very small volume within the atom.
Select the correct statement(s).
