Vedclass · Answer

(B) In the famous alpha-particle scattering experiment conducted by Geiger and Marsden under the supervision of Ernest Rutherford,they used a radioactive source that emitted alpha particles. The specific radioactive source used was $Polonium$ $(^{214}Po)$. This source provided a high-energy beam of alpha particles directed at a thin gold foil to observe the scattering patterns.
