in rutherfords experiment most of the alpha particles passed through the gold foil undeflected.what does this indicate
Answers
Answer:
Rutherford considered these observations and he concluded:
The fact that most alpha particles went straight through the foil is evidence for the atom being mostly empty space.
A small number of alpha particles being deflected at large angles suggested that there is a concentration of positive charge in the atom. Like charges repel, so the positive alpha particles were being repelled by positive charges.
The very small number of alpha particles coming straight back suggested that the positive charge and mass are concentrated in a tiny volume in the atom (the nucleus). The tiny number of affected particles means the chance of being on that exact collision course was very small, therefore the 'target' being aimed at had to be equally tiny.
