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 ?

Question

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 ?, The deflection of α-particles would be more pronounced in the aluminum foil due to its lighter atomic mass., The deflection of α-particles in the aluminum foil would be much less than in heavy foils, as lighter atoms offer less resistance to the passage of α-particles., There would be no significant difference in the deflection of α-particles between the aluminum foil and heavy foils, as the atomic mass of the foil material does not affect the scattering angle., The α-particles would not penetrate the aluminum foil and would be completely absorbed by it, resulting in no observable deflection.

Correct Option is : (B) The deflection of α-particles in the aluminum foil would be much less than in heavy foils, as lighter atoms offer less resistance to the passage of α-particles.
