What are the limitations of J.J. Thomson's model of the atom?
Answers
Thomson’s atomic model explained the overall neutrality of an atom. Its assumption that the total mass of an atom is uniformly distributed all over the atom was inconsistent with some of the experimental results. Rutherford’s gold foil experiment of scattering α-particles revealed that most of the space in an atom is empty contradicted Thomson’s atomic model. Thus, it was found that the plum pudding atomic model was insufficient to explain the structure of an atom
Solution : According to J.J. Thomson's model of an atom, 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 called the nucleus, and the electrons revolve around the nucleus.
