Rutherford's gold foil experiment concluded that most of the atom is:
AFilled with positive charge uniformly throughout
BEmpty space, with a tiny dense positively-charged nucleus
CMade of equal numbers of protons and neutrons mixed together
DMade of negatively charged electrons spread evenly across volume
Answer & Solution
Correct answer: B. Empty space, with a tiny dense positively-charged nucleus
Most alpha particles passed straight through the gold foil, meaning most of the atom is empty space. The tiny fraction that bounced back showed a small dense positively-charged nucleus at the centre.
