A group of students performed a computer simulation of Rutherford's gold foil experiment. They observed that most alpha particles passed straight through the gold foil, some were slightly deflected, and very few bounced back.
Answer the given questions with the right answers.
1. Why were only a few alpha particles deflected through large angles? -
2. Which conclusion about the nucleus is correct? -
3. Why was gold chosen for Rutherford's experiment? -
4. What caused the backward scattering of a very few alpha particles? -
