In Rutherford’s experiment, generally the thin foil of heavy atoms, like gold, plantinum etc. have been used to be bombarded by the a particles.If the thin foil of light atoms like aluminium etc. is used, what difference would be observed from the above results ?


#2

More number of a-particles will pass as the nucleus of the lighter atoms like aluminium is small, smaller number of a-particles will be deflected as the number of positive charges is less on the lighter nuclei.
