Dec 03, 2020· The main conclusions of Rutherford's experiment : Most of the space inside the atom is empty. Therefore, most of the a-particles went through the gold foil without deflecting from their path. There is a positive tiny part in the atom in its centre, which deflects or repels the a-particles. This must be containing the whole mass of the atom.
