Webplum pudding model (historical, physics) An obsolete scientific model of the atom, devised shortly after the discovery of the electron but before the discovery of the atomic nucleus, and according to which the atom is composed of electrons surrounded by a soup of positive charge to balance the electrons' negative charges. It was disproved in 1909. WebThis led Thomson to propose that atoms could be described as negative particles floating within a soup of diffuse positive charge. This model is often called the plum pudding …
