A.
$$\beta - $$ particles, which impinged on a metal foil and got absorbed
B.
$$\gamma - $$ rays, which impinged on a metal foil and ejected electrons
C.
helium atoms, which impinged on a metal foil and got scattered
D.
helium nuclei, which impinged on a metal foil and got scattered
Answer :
helium nuclei, which impinged on a metal foil and got scattered
Solution :
Rutherford's experiment was actually $$\alpha - $$ particle scattering experiment. $$\alpha - $$ Particle is doubly positively charged helium ion i.e., $$He$$ - nucleus.
