Answers
Hey mate...here is your answer

DRAWBACK OF THOMSON's MODEL OF AN ATOM....
Although Thomson's model explained that atoms are electrically neutral when the results of this model was carried by other scientist...
they concluded that Thomson's model didn't explain the stability of an atom...as atom is not neutral because the model have a positive and electrons are embedded on it...was incorrect...
BOHR's MODEL OF AN ATOM...
In order to overcome the objections raised against Rutherford's model of an atom
Neils Bohr put forward the following postulates about the model of an atom :-
1) Only certain special orbits known as discrete orbits of electrons are allowed inside the atom ...
2) While revolving in these discrete orbits the electrons do not radiate(loose) energy , so they can't fall into the nucleus...when they loose energy...they are stable at their place...
3) These orbits or shells are called Energy Level.
4) Neils Bohr got Nobel Prize for his work on the structure of an atom in 1922 ...
I HOPE IT WILL HELP YOU...
Thomson is only for the the the light then no what is question tell plz
