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.

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.

the atomic number will stay the same no matter how many electrons it has, so it doesn’t decrease nor increase. it’ll only change with a different number of protons
