प्रश्न
Why did Rutherford select a gold foil in his α–ray scattering experiment?
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.
