Rutherford's gold foil experiment led to the notion that the atom contains an extremely small, positively charged nucleus. In this experiment, alpha particles were fired at a thin gold foil, and while most of the particles went straight through, some were deflected at large angles or even bounced back. This led Rutherford to conclude that atoms contain a small, dense nucleus with a positive charge, surrounded by a cloud of negatively charged electrons.
