Rutherford's scattering experiment

3D Model

There are two animations. Select at bottom of model. This is the setup Rutherford has used. Radioactive material is used to emmit alpha particles. A beam of these alpha particles are directed to the gold foil in the middel. Most of the particle pass through the gold foil without being deflected. From this observation Rutherford concluded that most of the gold atoms must consist of empty space. The atoms’ mass is concentrated in the middel.
