Answer :
Final answer:
Ernest Rutherford's gold foil experiment revealed atoms have small, dense, positive nuclei, reshaping atomic theory.
Explanation:
Ernest Rutherford's gold foil experiment provided key insights into the structure of an atom. The experiment showed that
- Atoms have small, dense, positive nuclei, which was a groundbreaking conclusion drawn from the deflection of alpha particles in the gold foil.
- Atoms contain negatively charged particles was not directly proposed as a conclusion from this experiment.
Rutherford's findings revolutionized the understanding of atomic structure.
