. What observations were noticed by Rutherford during alpha particle scattering experiment?


Best Answer

When fast moving alpha particles were allowed to strike a very thin gold foil in vacuum, Rutherford noticed that:

(i)Most of the alpha particles passed straight through the gold foil without any deflection from their original path.

(ii)Few alpha particles were deflected through small angles and very few were deflected through large angles.

(iii)Very few (about 1 in 20,000) alpha particles completely rebounded on hitting the gold foil and turned back on their path.
