An experiment was conducted by Rutherford to provide a model for the atom. This was known as nuclear type of model of atom.

In this experiment conducted by him, alpha particles were made to hit the sheet of thin foil of gold.

In the observation of the experiment, it was observed that very little rays deflected at 180 degree. So from this observation, he concluded that there is a core called nucleus at the centre of atom which is positively charged.
