Question

What were the conclusion of rutherford alfa particles scattering experiment

Answer 1

among the 20,000 alpha particles...
some are deflected in larger angles
some r deflected in smaller angles
and one among the 20,000 alpha particles deflected in 180 degrees..
so he concluded that atom consists of a nucleus and electrons are revolving around it..

Answer 2

■ Most of the space inside the atom is empty because most of the the alpha particles passed through the gold foil without getting deflected.
■ Very few particles were deflected from their path ,indicating that the positive charge of the atom occupies very little space.
■ A very small fraction of Alfa particles were deflected by 180 ° ,indicating that all the positive charge and mass of atom were concentrated in a very small volume within the atom.
