Which of these was a characteristic of the rutherford model of the atom, but not the thomson model? (2 points) a. negatively charged electrons b. positive charge concentrated at the center of the atom c. equal positive and negative charges d. indivisible atoms

Thomsons model( commonly the plum pudding model) - can also be described by a watermelon cut horizontally. The red of the water melon is a positively charged cloud with the seeds representing the negatively charged electrons sprinkled through out the positive cloud.
