Most of the particle either passed straight through the metal foil or suffered only small deflection. This could be explained by Thomson's Atomic Model. A few particle were deflected through angle where were less than 90 degree and a very few particle were deflected through an angle greater than 90 degree ().Sometimes a particle was found to be deflected through 180 degree( ) .

Rutherford - an overview | ScienceDirect Topics

In brief, Rutherford bombarded very thin gold foil (4 × 10 −5 cm thick) with alpha particles. Most of the alpha particles traversed the gold foil almost as if the foil was not in their path; however, one alpha particle for every 20,000 particles would bounce back from the foil by more than 90 degrees from the direction of travel.
