What are the conclusions of the Gold foil Experiment?

Solution

Gold-foil experiment:

  • Gold-foil experiment was given by Rutherford.
  • In his experiment, the α-particles were made to come down on a thin gold foil.
  • Many of the α-particles passed linearly through the gold foil.
  • Some of the particles deviated at small angles.
  • One out of every 12000 particles appeared to bounce.

Conclusion of Rutherford's model of an atom:

  • The space inside an atom is almost empty as most of the α-particles passed without deflection through the gold foil.
  • The positive charge occupies a minimum space which indicates that very few particles were diverted from their path.
  • A very small proportion of α-particles were diverted by 180o, indicating that all the positive charge and mass of the gold atom were concentrated in a very small volume within the atom.
