JJ Thomson's 1904 model was called the "plum pudding model." This model described the atom as a sphere of positive charge with electrons embedded throughout, like plums in a pudding. It was later replaced by the more accurate Rutherford model.
Thomson's plum pudding model is the model of an atom in which an atom is regarded as a sphere of size 10^(-10)m radius and positively charged matter in which electrons were embedded. Thomson used the pudding as the positive charge and the plums as the negative charge. The plums are stuck in the pudding just as electrons are randomly found in an atom.
Hepostulated (he was wrong) the existence of a 'sticky' substance like pudding that had a positive charge that the electrons was stuck in. Like plum pudding. Electrons were like plums actual particles with negative charges. The pudding was just a smear of stuff with a positive charge and held the atom together.
In Thomson's plum pudding model, the mass of the atom is spread out uniformly throughout the positively charged sphere, similar to plums in a pudding. This model proposed that electrons were embedded in the positive sphere like plums in the pudding, representing the negative charges.
Thompson described his model as plum pudding. Since not many people even know what plum pudding is, i like to describe his model as a scoop of chocolate chip ice cream. Imagine the vanilla ice cream as the positive material and the chips as the negative material.

The Plum Pudding Model proposed by J.J. Thomson depicts electrons as dispersed throughout a positively charged atom, much like plums in a pudding. This model suggested that the atom is overall electrically neutral due to the balance of positive and negative charges. However, this model was later replaced by the Rutherford model which proposed a nucleus at the center of the atom surrounded by orbiting electrons.
J.J. Thomson proposed the "plum pudding" model of the atom, where electrons were embedded in a positively charged sphere, similar to plums in a pudding. This model suggested that the atom was a uniform, positively charged structure with negatively charged electrons scattered throughout.
