Question

What conclusion was drawn by Rutherford from his $\alpha$ -particle scattering experiment?

Answer 1

Conclusion of Rutherford's scattering experiment:

1) Most of the space inside the atom is empty because most of the $\alpha$-particles passed through the gold foil without getting deflected.

2) Very few particles were deflected from their path, indicating that the positive charge of the atom occupies very little space.

3) A very small fraction of $\alpha$-particles were deflected by very large angles, indicating that all the positive charge and mass of the gold atom were concentrated in a very small volume within the atom.
