Answer 1

Question :

What would have been the observation if a foil of some other metal was used instead of a gold foil in Rutherford's experiment?

To find :

The observation of Rutherford's Experiment

Solution :

The observations were made from the experiments are :

✓ About 99 % of the alpha particles went straight through the file and did not deflect.

✓ Some the particles get deflected from their original parts through small angles.

✓ A very small number of the alpha particles could not proceed through the foil and appeared to rebound.

Know More :

Conclusion of Rutherford's Experiment are :

✓ Since most of the alpha particles went straight without getting deflected it indicates that most of the space inside the atom is empty.

✓ Very few particles were deflected from their path. This shows that, the positive charge of the atom occupies very little space.

✓ The strong deflection or even bouncing back of particles indicated that all the positive charge and mass of the atom is concentrated in a very small volume within the atom.

Drawbacks of this Experiment :

✓ Atom as we know is three dimensional but Rutherford's model was two dimensional.

✓ Rutherford could not explain the atomic spectrum.

✓ Rutherford could not explain the stability of an atom.
