Alpha particles were deflected by the positively charged

See explanation

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.
