Rutherford's `alpha` particle dispersion experiment concludes

Options

A. All positive ions are deposited at small part
B. All negative ions are deposited at small part
C. Proton moves around the electron
D. Neutrons are charged particles

Answer

A

Explanation

Conclusions of Rutherford.s gold foil experiment:
Most of the space inside the atom is empty because most of the a-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.
