Question

PLS HELP ME After completing the Gold Foil Experiment, Ernest Rutherford proposed that the positive charge of an atom was concentrated in a dense central core or
nucleus. What evidence from the experiment did he use to support this idea? Your answer should reference the image.

Answer 1

Answer:

A piece of gold foil was hit with alpha particles, which have a positive charge. Most alpha particles went right through. This showed that the gold atoms were mostly empty space. Some particles had their paths bent at large angles. A few even bounced backward. The only way this would happen was if the atom had a small, heavy region of positive charge inside it.
