Question

What is Rutherford's scattering experiment?what are it's conclusions?

Answer 1

Conclusion of Rutherford's scattering experiment:

Most of the space inside the atom is empty because most of the α-particles passed through the gold foil without getting deflected.

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

A very small fraction of α-particles were deflected by very large angles, indicating that all the positive charge and mass of the gold atom were concentrated in a very small volume within the atom.

From the data he also calculated that the radius of the nucleus is about 105times less than the radius of the atom.

Answer 2

CONCLUSIONS DRAWN BY RUTHERFORD FROM HIS A-RAY SCATTERING EXPERIMENT.

Rutherford concluded from the a-praticle scattering experiment that :

1) Most of the space inside the atom is empty because most of the a-praticles 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 a-praticles were deflected by 180° , indicating that all the positive charges and mass of the gold atom were concentrated in a very small volume within the atom .
