Answer:
A few of the positive particles aimed at a gold foil seemed to bounce back.
Explanation:
Rutherford gold foil experiment led to the discovery that every atom has a nucleus, its mass and all the positive charge are concentrated in it and also that most of the atom is mostly empty space.
It was performed in 1911 by Rutherford and his coworkers Ernest Marsden and Hans Geiger. They bombarded fast moving alpha particles on thin sheets of gold foil.
Most of the alpha particles passed through the sheet while few were deflected from their straight path. A small percentage of particles also bounced back from the foil. Since the alpha particles are positive so there must have been something positive inside the atoms that deflected and bounced back the alpha particles. So it led to the conclusion that the center of atom is positively charged.
