उत्तर

  1. Most of the space inside the atom is empty became most of the α-particle passed through the gold foil without getting deflected.
  2. Very few particles were deflected from their path, indicating that the positive charge of the atom occupies very little space.
  3. A very small fraction of α-particle were deflected by very large angles, indicating that all the +ve charge and mass of the gold atom were concentrated in a very small volume within the atom.
