Question

describe in brief the Rutherford's alpha particle scattering experiment

Answer 1

Rutherford take a very thin gold foil of 1000 atom.when fast moving alpha particles are allowed to strike a very thin gold foil in vaccum it is found that:
(1) most of the alpha particles pass straight through the gold foil without any deflection from their original path.
(2) a few alpha particles are deflected through large angles.
(3) a very few alpha particles completely rebound on hitting the gold foil and turn back on their path.

Answer 2

It is the experiment that is famous for proving that an atom must have a nucleus. In the experiment Rutherford fired positively charged particles at a thin sheet of gold foil. When he did this, he observed that some of the positive particles went straight through the gold atoms in the foil, while others rebounded back.
