Question

Explain Rutherford’s α -particle scattering experiment and give its
observation and conclusion drawn.

Answer 1

Answer:

Answer

Rutherford passed beams of alpha particles through a thin gold foil to observe the atom and noted how the alpha particles scattered from the foil.

Observations of Rutherford's alpha ray scattering experiment:

• Most of the alpha -particles passed straight through the gold foil without any deviation.
• . Some of the -alpha particles were deflected by the foil by some angles.
• Interestingly one out of every 12000 alpha particles appeared to rebound

The four major Conclusion of Rutherford's scattering experiment:

• Most of the space inside the atom is empty because most of the -alpha 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 -alpha 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.
• . He also concluded that radius of nucleus is about 105 times less than the radius of atom

Answer 2

Rutherford passed beams of alpha particles  through a  thin gold foil and noted how the alpha particles scattered from the foil.

Observations of Rutherford's alpha ray scattering experiment:

1. Most of the α-particles passed straight through the gold foil without any deviation.

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

3. Interestingly 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.
