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? he proved that the nucleus is small, dense, and positively charged and that the atom is composed of mostly empty space. he proved that the nucleus is small, dense, and negatively charged, and that the atom is composed of mostly empty space. he proved that the nucleus is large, dense, and positively charged and that the majority of the atoms volume is taken up by the nucleus. he proved that the nucleus is large, dense, and negatively charged and that the majority of the atoms volume is taken up by the nucleus.

Explanation:

Rutherford's gold - foil experiment showed that most alpha particles passed straight through the foil, indicating that the atom is mostly empty space. A small fraction of alpha particles were deflected or bounced back, proving 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.
