Thomson's Model of the Atom


 Thomson suggested in 1898  that the atom is a positively charged solid sphere and electrons are embedded in it in sufficient number so as to make the atom electrically neutral. One can compare Thomson's atom to a birthday cake in which cherries are embedded. This model was quite attractive as it could explain why only negatively charged particles are emitted when a metal is heated and never the positively charged particles.
