In Rutherfords experiment, generally the thin foil of heavy atoms, like gold, platinum etc. have been used to be bombarded by the 'alpha' -particles. If the thin foil of light atoms like aluminium etc. is used, what difference would be observed from the above results?

During Rutherford alpha - ray experiment, it was observed that most of the alpha particles passed through the Gold foil without any deflection, a small fraction deflected by small angles and very few bounced back. b) Give the atom model proposed by him.

During Rutherford alpha - ray experiment, it was observed that most of the alpha particles passed through the Gold foil without any deflection, a small fraction deflected by small angles and very few bounced back. c) What are the main drawbacks of this model and how Niels Bohr overcome these defects in his model?

During Rutherford alpha - ray experiment, it was observed that most of the alpha particles passed through the Gold foil without any deflection, a small fraction deflected by small angles and very few bounced back. a) What are the main conclusions made by Rutherford?

In Geiger-Marsden Scattering experiment alpha per ticles of 5.5 MeV is allowed to fall on a thin gold foll of thickness 2.1 * 10^-7m. Why gold foil is used in this experiment?
