NEET Physics: Physics Class 12: Atomic Physics questions with solutions

Q1. Which of the following was not a conclusion of Rutherford's gold foil experiment?

1. The atom is mainly empty space.
2. The nucleus has a negative charge
3. The atom has a dense nucleus.
4. Alpha particles can pass through a thin sheet of gold foil E. All of the above are correct regarding the gold foil experiment.

Answer: The nucleus has a negative charge

Rutherford concluded that atoms are mostly empty space and contain a small, dense, positively charged nucleus. Therefore, saying the nucleus has a negative charge is not one of his conclusions.
