प्रश्न
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?

उत्तर १
- The observation would not change if the α-scattering experiment were carried out using a metal foil rather than gold.
- In the α-scattering experiment, a gold foil was taken because gold is malleable, and a thin foil can be easily made.
- It is difficult to make such foils from other metals.
उत्तर २
The observation will be the same whether the foil is made of heavy metals such as gold (e.g., platinum, silver), but if the foil is made of light metal (e.g., sodium, magnesium), the massive a-particles may push the nucleus aside and cannot be deflected back.
