text: Until Rutherford’s efforts, a popular model of the atom had been the so-called “plum-pudding” model, advocated by the English physicist Joseph John Thomson, which held that each atom consists of a number of electrons (plums) embedded in a gel of positive charge (pudding); the total negative charge of the electrons exactly balances the total positive charge, yielding an atom that is electrically neutral.
text: In this model, the atom is a ball of positive charge -- the pudding -- in which the electrons -- the plums -- are located.
