J. J. Thomson - Wikipedia
WEBSir Joseph John Thomson OM FRS [1] (18 December 1856 – 30 August 1940) was a British physicist and Nobel Laureate in Physics, credited with the discovery of the electron, the first subatomic particle to be found.
Thompson Atomic Model: Description, Limitation & Significance
WEBFollowing his discovery of the electron in 1897, British Physicist J.J. Thomson proposed a model of the atom in 1904 after doing a series of cathode tube experiments. According to his hypothesis, an atom consists of positive and negative charges present in equal amounts so that it is electrically neutral.
Plum pudding model - Wikipedia
WEBThomson's plum-pudding model of the atom is one of a series of atomic models ranging from the philosophical models of the ancient Greeks through John Dalton's chemistry-based atom to the modern quantum atom of atomic physics. Among these models, Thomson's can be considered the first modern model.
