Question

1. ernest rutherford was the first scientist to demonstrate the structure of the atomic nucleus when he bombarded a thin layer of gold foil with a stream of high - velocity, positively charged alpha particles, as indicated by the arrows. what conclusions did rutherford come to as a result of his experimental data?

Explanation:

Rutherford's gold - foil experiment showed that most of the alpha particles passed straight through the gold foil, indicating that the atom is composed of mostly empty space. Some alpha particles were deflected at large angles, which proved that the nucleus is small, dense, and positively charged.

Answer:

He proved that the nucleus is small, dense, and positively charged, and that the atom is composed of mostly empty space.
