In Rutherford’s experiment, generally the thin foil of heavy atoms, like gold, platinum etc. have been used to be bombarded by the a-particles. If die thin foil of light atoms such as aluminuim is used, what differnce would be observed from the above result ?
If A1 is used, deviation of a particles will be comparatively less because nuclear charge in AT is less as compared to that in Au, Pt etc. Number of particles deflected back and deflected through some angles wil be negligible due to less +ve charge in nucleus
