Rutherford did an experiment. In this experiment fast moving alpha(doubly charged helium ions) particles were made to fall on gold foil. OSREVATIONS OF MODEL. 1.There is a positively charged centre in an atom called nucleus. Nearly all the mass of the atom resides in its nucleus. 2.The electrons revolve around the nucleus in circular paths. 3.The size of the nucleus is comparatively very small to that the size of atom.

Rutherford model is also called nuclear model of an atom . he gave us a nucleus of an atom. He told that the size of nucleus is very small as compared to atom. The electrons revolved around nucleus. This explain their model by an experiment pf gold foil

Earnest Rutherford gave the atomic model which described the presence of nucleus . He made the fast moving alpha particles pass from the gold foil and following observations were noticed: 1. Most of the alpha particles passed straight through the foil concluding that most of the space inside the atom is empty. 2. Few particles were deflected at smaller angles concluding that the positive space in an atom occupies very little space. 3. Few particles were completely bounced back concluding that the mass of the atom is concentrated in a small volume within the nucleus.
