10. Base your answer to the following question on the information below.
In 1897, J. J. Thomson demonstrated in an experiment that cathode rays were deflected by an
electric field. This suggested that cathode rays were composed of negatively charged particles found
in all atoms. Thomson concluded that the atom was a positively charged sphere of almost uniform
density in which negatively charged particles were embedded. The total negative charge in the atom
was balanced by the positive charge, making the atom electrically neutral.
In the early 1900s, Emest Rutherford bombarded a very thin sheet of gold foil with alpha
particles. After interpreting the results of the gold foil experiment, Rutherford proposed a more
sophisticated model of the atom,
