- Following 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.
