Experimental basis for the model. Rutherford overturned Thomson's model in 1911 with his well-known gold foil experiment in which he demonstrated that the atom has a tiny and heavy nucleus. Rutherford designed an experiment to use the alpha particles emitted by a radioactive element as probes to the unseen world of atomic structure. If Thomson was correct, the beam would go straight through ...

The Rutherford model was devised by the New Zealand-born physicist Ernest Rutherford to describe an atom.Rutherford directed the Geiger–Marsden experiment in 1909, which suggested, upon Rutherford's 1911 analysis, that J. J. Thomson's plum pudding model of the atom was incorrect. Rutherford's new model for the atom, based on the experimental results, contained new features of .

Ernest Rutherford was interested in knowing how the electrons are arranged within an atom. Rutherford designed an experiment for this. In this experiment, fast moving alpha (α)-particles were made to fall on a thin gold foil. He selected a gold foil because he wanted as thin a layer as possible. This gold foil was about 1000 atoms thick.

A plum pudding was a Christmas cake studded with raisins ("plums"). So think of the model as a spherical Christmas cake. When Rutherford shot α particles through gold foil.

The Foil. A single atom is too small to look at. It would be impossible to get 'just one' to examine. Therefore Rutherford decided to look at a metal foil consisting of many atoms in a very thin sheet. Gold was the ideal choice as gold can be rolled out into very fine gold leaf sheets. These very fine sheets are only a few atoms deep.

Rutherford planned to test Thomson's hypothesis and model by doing and experiment called the Gold Foil Experiment. So the experiment was conducted with a source that gave off positively charged alpha particles towards a gold piece of foil. There was a ring around the foil that acted as a detector to see where the alpha particles ended up.
