प्रश्न
Why did Rutherford select a gold foil in his α–ray scattering experiment?
Advertisements
उत्तर
Gold is a heavy metal with high mass number. A light metal cannot be used because on being hit by fast moving α-particles, the atom of light metal will be simply pushed forward and no scattering can occur. Moreover, gold is highly malleable and can be beaten to get very thin foils.

What do you think would be the observation if the α-particle scattering experiment is carried out using a foil of a metal other than gold?
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?
