Question

What are the limitations of J.J. Thomson's model of the atom?

Answer 1

Postulates of J.J Thomson's model of an atom:

• An atom contains a positively charged sphere and the electrons are placed in it.
• The magnitude of positive and negative charges is equal. Due to this, an atom is electrically neutral.

Limitations of J.J Thomson's model of an atom:

• Thomson’s model failed to explain the results of the alpha particle scattering experiment that was given by Rutherford.
• One of the major drawbacks of his model is that there were no experimental pieces of evidence provided by him.
• He failed to explain the stability of atoms.
