Use Rutherford's gold-foil experiment to answer each of the following: How did the results differ from what he expected? Check all that apply. The particles reacted with gold atoms, having formed a new compound. The particles were deflected from their straight paths as they passed through the gold foil. The particles reflected from the gold foil and went back in the opposite direction. The particles stopped moving after touching the gold foil.
