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

Answer :

J.J Thomson considered atom as sphere of uniform distributed positive charge and electrons are embedded in it as shown in figure.


The Limitation of this model are as follows.


1. J.J Thomson's model of the atom could not explain the results of Alpha particle scattering experiment carried out by Rutherford.


2. According to Thomson’s an atom consists of a positively charged sphere with electrons embedded in it. However, it was later found that the positively charged particles reside at the centre of the atom (nucleus), and the electrons revolve around the nucleus.


3. J.J Thomson's model of the atom was just based on imagination it did not have any experimental evidence in its support like the Rutherford's Model of the atom.
