Question

What was the major conclusion from Rutherford’s gold foil experiment?
Options
A Atoms are indivisible.
B Electrons are spread uniformly throughout an atom.
C Most of an atom is empty space with a dense nucleus.
Correct Answer
D Electrons orbit the nucleus in fixed paths.
Correct Answer

Option C is the correct answer.

Detailed Explanation

Rutherford's experiment showed that most alpha particles passed straight through the gold foil (empty space), but a few were deflected at large angles, indicating a small, dense, positively charged nucleus at the center.

Hint

The fact that some particles bounced back suggested a very small, massive core.
