1. 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.
2. Limitations of Rutherford's model of the atom:
1. His model failed to explain the stability of atoms.
2. The arrangement of electrons in a circular path was not defined.
3. Any particle that is moving in a circular path would undergo acceleration and radiates energy.
In Rutherford's 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. α-particles are doubly-charged helium ions.
