can a thin foil of aluminium be used in place of gold in rutherford experiment? give suitable explanation.

Solution

No, a thin film of Aluminium can not be taken in the experiment because-
1) Aluminum is less ductile, hence such thin foil will not be formed as the experiment requires.
2) The atomic size of Aluminum is very small which will cause much scattering and very less amount of rays will be able to strike the atoms of Aluminum.
And due to these factors failure of the experiments will be caused.

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