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.

Answer

Answer:

B. A few positive particles bounced back because they were pushed away from the positive center.

Explanation:

Step1: Recall Rutherford's experiment

In Rutherford's gold - foil experiment, positively charged alpha particles were shot at a thin gold foil.

Step2: Understand the atom model

Rutherford's model had a small, dense, positively - charged nucleus at the center of the atom.

Step3: Analyze particle behavior

Like charges repel. Positive alpha particles that came close to the positive nucleus were repelled and bounced back. Most particles passed through because the atom is mostly empty space, but the key surprising result was the few particles that bounced back due to the positive - positive repulsion from the nucleus.
