![]() Some of the limitations of Thomson’s Atomic Model are: Thomson’s atomic model had several limitations that were eventually overcome by further research and the experiments of various scientists later on. Thomson’s model is also called Plum Pudding Model or Watermelon Model. An atom is an electrically neutral quantity and the total positive charge of the atom is balanced by the total negative charge in the atom.The positive charge of the sphere is uniformly distributed to balance the negative charge of the electrons. An atom consists of a positively charged sphere or cloud in which negatively charged electrons are embedded.Various Postulates of Thomson’s Atomic Model are mentioned below: The diagram explaining the Plum Pudding Model or the Thomson Atomic model is added below which shows that positive charge is spread throughout the atom and negative charge is embedded in the atom maintaining the electrical neutrality of the atom. We can also compare this with a watermelon where the positive charge is comparable to the edible part of the watermelon, and electrons are like seeds that are embedded in that sphere. Thomson’s Atomic Model, also called the Plum Pudding Model states that an atom can be compared to a plum pudding where electrons are like dry fruits in a sphere of positive charge, representing the pudding. The magnitude of the positive and the negative charge in the sphere is equal according to Plum Pudding Model. In this sphere, the positive charge is spread uniformly and the negative charge is embedded in this positive charge due to electrostatic attraction between the charge. According to Thomson, an atom represents a sphere of radius of magnitude in Angstrom. Thomson Atomic Model is also called the Plum Pudding model as it represents the Plum Pudding.
