Therefore, he reasoned that there must be a source of positive charge within the atom to counterbalance the negative charge on the electrons. This led Thomson to propose that atoms could be described as negative particles floating within a soup of diffuse positive charge.

WebIn 1898, J. J. Thomson proposed the first of many atomic models to come. He proposed that an atom is shaped like a sphere with a radius of approximately 10 -10 m, where the positive charge is uniformly distributed. The electrons are embedded in this sphere so as to give the most stable electrostatic arrangement. Web8 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.
