Question

describe the observation conclusion and planetary model of atoms given by Rutherford​

Answer 1

Observations of Rutherford's scattering experiment

1. Most of the fast moving α-particles passed straight through the gold foil.

2. Some of the α-particles were deflected by the foil by small angles.

3. Surprisingly one out of every 12,000 alpha particles appeared to rebound

Conclusion of Rutherford's scattering experiment:

1. Most of the space inside the atom is empty because most of the α-particles 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-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.
