Final answer:
Thomson's plum pudding model of the atom describes electrons embedded within a uniform positive charge, akin to chocolate chips in a cookie, where the dough represents positive charge and the chips resemble electrons.
Step-by-step explanation:
Thomson's model of the atom can be likened to a chocolate chip cookie in that the electron particles are similar to the chocolate chips embedded throughout a cookie. In Thomson's plum pudding model, electrons are thought to be scattered within a uniform sphere of positive charge, just as chocolate chips are spread within the dough of a cookie. This model illustrates how atoms are composed of negatively charged electrons within a positive charge that balances out to make the atoms electrically neutral. Thomson's non-nuclear model represented a solid sphere of positive matter with the electrons capable of moving to some extent. Similar to how chips in a cookie dough might shift slightly, electrons in Thomson's model could move closer to or further from the center of the atom, depending on the electric charge distribution.
