Step-by-step explanation:
In Rutherford's experiment, a gold foil was bombarded with positively charged alpha particles. A zinc sulphide screen was used to observe the movement of the alpha particles during the experiment.
A few particles passed through without deflection while some particles were deflected through large angles. This observation led Rutherford to the conclusion that the atom was made up of a dense positively charged nucleus where most of its mass was concentrated.
