A few years later, in 1904, Thomson, based on his experiments with cathode ray tubes, proposes the Plum Pudding Model of the atom, which suggests that the atom is made up of a positively-charged sphere or diffuse with negatively-charged electrons scattered all around the diffuse, similar to the way raisins are scatted in a pudding. ... Specifically, the nuclear model states that all the positively-charged particles of the atom and a large part of its atomic mass are concentrated at the center of the atom, the nucleus, while the negatively-charged particles, the electrons, orbit the nucleus a...
