2.he selected a gold foil because he wanted as thin layer as possible. the gold foil was about 1000atom thick.
3. alpha particle are doubly charged helium ion since they have a mass 4u they have considerable amount of energy .
4. it was aspected that alpha particle will deflected by sub atomic particles in gold atom since the alpha particle are much heavier than protons
