Answer:
B. A few positive particles bounced back because they were pushed away from the positive center.
Step-by-step explanation:
The result of the experiment conducted by Rutherford shows that a few positive particles bounced back because they were pushed away from the positive center.
This is the central theme of Rutherford's experiment on a thin gold foil.
- In 1911, Rutherford performed the gold foil experiment that gave the modeling of the atomic structure a great boost.
- He bombarded a thin gold foil with alpha particles.
- He discovered that most of the alpha particles passed through the foil while a few of them were deflected back.
- This led him to postulate that an atom has a small positively charged center where nearly all the mass is concentrated.
