Nov 21, 2017· Rutherford model of atom describes that the atom is composed of an atomic nucleus and electrons surrounding the nucleus. This model caused to reject the Thomson model of atom. Rutherford model was proposed by Ernst Rutherford after the discovery of the atomic nucleus. The gold foil experiment was used by Rutherford to propose this atomic model.

The gold atom has a positive charge of 79e (balanced of course by that of the 79 electrons in its normal state). Neglect the electrons—they'll be scattered away with negligible impact on the heavy alpha.
