Rutherford used positively charged particles to investigate the structure of the atom. the results surprised him, and he developed the atomic model shown below. what surprising result is explained using this model? a few positive particles bounced back because they bounced off of the net formed by the ovals. a few positive particles bounced back because they were pushed away from the positive center. most positive particles passed through because of the empty space between the outer edge and the center. most positive particles passed through because they were attracted by the small particles moving around the center.
