explain how the rutherford gold foil experiment correctly advanced atomic theory away from the plum pudding model.\na it proved the atom contained positive and negative charges.\nb it proved the atom contains protons, electrons, and neutrons.\nc it proved that atoms are spherical in shape and not shaped like pudding.\nd it proved the positive charge is concentrated in a relatively small region of the atom.

Answer

Brief Explanations:

The plum - pudding model proposed a uniform distribution of positive charge with electrons embedded. Rutherford's gold foil experiment showed that most alpha particles passed through the gold foil, but some were deflected at large angles. This indicated that the positive charge and most of the mass were concentrated in a small nucleus, rather than being uniformly distributed as in the plum - pudding model.

Answer:

D. It proved the positive charge is concentrated in a relatively small region of the atom.
