Question

Cite the three pieces of evidence that caused Rutherford to conclude that the atom had a tiny, positively charged center (nucleus).

Answer 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.)
