Geiger–Marsden experiment

The Geiger–Marsden experiment (also called the Gold foil experiment or the Rutherford experiment) was a scientific experiment done by Hans Geiger and Ernest Marsden in 1909. Supervised by their instructor, Ernest Rutherford, the experiment happened at the Physical Laboratories of the University of Manchester, in England. The results of the experiment were surprising: The experiment showed scientists that the atomic nucleus exists, thus disproving the plum pudding model of the atom. This led to the creation of the Rutherford atomic model (also called the planetary model of the atom).
