Question:

If you could ask Rutherford one question about his work, what would it be? [Pg. No. 144]

Answer: Verified

If I could ask Rutherford one question about his work, I would ask:

'How did you feel when a few alpha particles bounced back from the gold foil, even though most scientists expected them to pass straight through?'

This question is important because that unexpected observation led Rutherford to reject Thomson's model and propose that an atom has a small, dense, positively charged nucleus.
