Dear student. Advantages of Thomson's atomic model:- a) It successfully explained electron neutrality of an atom. b)It was the first attempt in identifying structure of an atom and presence of large positive charge holding sphere in which electrons were embedded. Disadvantages of Thomson's model:  It could not explain:- a)the stability of an atom  b)the origin of atomic spectral lines. c)the large angle of scattering of alpha particles. Regards.
