• Rutherford disproved the plum pudding model with his gold foil experiment.

• Since most of the particles passed straight through the foil, he confirmed that atoms are mostly made of empty space.

• Because only a small number of particles were deflected at large angles, that meant there was a central positive charge- the nucleus.

• He claimed that electrons revolved in a circular motion around the nucleus, much like a solar system.

CONCLUSION
