1.Thomson model of an atom could not explain stability of atom 2.it could not explain the hydrogen spectrum 3.his proposition that the positive charges in which negatively charged electrons are embedded is found to be irrelevant.

Thomson model of an atom:-
An atom posses a spherical shape in which the shape in which the positively charge is uniformly distributed. The electrons are embedded into such a manner as to give the most stable electrostatic arrangements. This model was much like raisins in a pudding and is known as THOMSON'S PLUM PUDDING MODEL.

✔ Though this model was able to explain the overall neutrally of the atom.
✔It could not satisfactorily explain the results of scattering experiments , carried out by RUTHERFORD in 1911 and was rejected.
✔ This model was discarded as it was not consistent with the results of further investigations such as scattering of
α (alpha ) - particles by thin metal foils.
