Rutherford Atomic Model electrical4u.com

Thomson Model of Atom J.J. Thomson, the discoverer of electron in 1898 proposed the ‘raisin pudding’ model of atom. He assumed that an atom consists of a uniform sphere of positive charge with electrons embedded into it in such a way as to give it a stable configuration. In this model, the atom is visualized as a pudding or cake of positive charge with raisins (electrons) embedded into it

Thomson's plum pudding model was disproved in 1909 by one of his former students, Ernest Rutherford, who discovered that most of the mass and positive charge of an atom is concentrated in a very small fraction of its volume, which he assumed to be at the very center.
