However, its propositions were not consistent with the results of later experiments. Thomson’s atomic model was successful in explaining the overall neutrality of the atom. Therefore, this model is also referred to as the watermelon model, the plum pudding model or the raisin pudding model.Īn important aspect of this model is that it assumes that the mass of the atom is uniformly distributed over the atom. Thomsons’ atomic model Doesn’t the figure above remind you of a cut watermelon with seeds inside? Or, you can also think of it as a pudding with the electrons being the plum or the raisins in the pudding.
