Given below is an illustration that compares the plum pudding model of an atom to what Rutherford observed in his experiment. The top structure shows how the alpha particles would have passed through the gold foil atoms if the plum pudding model was correct in its assumptions.
What did Rutherford's gold foil experiment illustrate about the atom? It showed that the positive charge was concentrated in a very small area, rather than being spread out. We now call this small area the nucleus.

Rutherford's Gold Foil Experiment The Gold Foil Experiment Ernest Rutherford Scientific Background So far, the most up-to-date and "accurate" model of the atom was J.J. Thompson's Plum Pudding Model.
This theory proposed that the electrons where evenly distributed throughout an atom. Since an alpha paritcle is 8,000 times as heavy as an electron, one electron could not deflect an alpha particle at an obtuse angle.
Rutherfords experiment consistent of bombardment of a gold foil by alpha particles and then measurement of the deviation of the alpha particles. The direction of deviation indicated the charge in the region of the atom.

Rutherford inferred from the results of his gold foil experiment that the positive charge and mass of an atom are concentrated in a very small area in the center, and that atoms are mostly empty space.
The Gold foil experiment was an experiment done by Ernest Rutherford to determine the layout of the atom. Until that time, the prevailing theory was the Plum pudding model of the atom.
