Answer:
Rutherford’s experiment
Rutherford performed the experiment by bombarding a thin sheet of gold with α- particles and then analysed the trajectory of these particles post interaction with gold foil.
Rutherford’s model of the atom-
An atom consists of a very small-sized nucleus with a positive charge. It has electrons revolving around this nucleus in specific orbits. All the mass of an atom resides in the nucleus. This experiment does not explain the stability of the atom.
Limitations of Rutherford’s experiment
- The experiment does not give an idea about the arrangement of the electrons in the orbit.
- Rutherford’s model did not describe the stability of an atom.
- According to his model, the electrons revolve in a circular path around the nucleus. So, particles in motion would undergo acceleration that causes radiation of energy by charged particles. This will lead to the loss of energy of electrons and fall into the nucleus.
