WebbThe plum pudding model depicts the electrons as negatively-charged particles embedded in a sea of positive charge. The structure of Thomson's atom is analogous to plum pudding, an English dessert (left). Image from Openstax, CC BY 4.0. Webb8 apr. 2024 · J. J. Thomson, who invented the electron in the year 1897, suggested the atom's plum pudding model in 1904 which was for including the electron in the atomic model. The electrons were assumed to be positioned in revolving circles around the atom in this model to be having a "cloud" of positive charge. JJ Thomson Proposed that an …

The plum pudding model is one of several historical scientific models of the atom. First proposed by J. J. Thomson in 1904 soon after the discovery of the electron, but before the discovery of the atomic nucleus, the model tried to explain two properties of atoms then known: that electrons are negatively charged particles and that atoms have no net electric charge. The plum pudding model has elect…
