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

Text Solution

Verified by Experts

On using the foil of heavy metal like gold (e.g., platinum, silver etc.) the observation will be same but if the foil is of light metal (e.g., sodium, magnesium etc.), the massive a-particles may push the nucleus aside and may not be deflected back.
