  1. 1. What about most of the alpha particles going through without being deflected at all (the atoms was mostly space?)
    2. A few alpha particles were deflected or reflected.
    (a. There was a central portion of the atom where most of the mass was concentrated.)
    (b.) The alpha particles were positively charged; therefore, the core of the atom was positively charged.)
