Rutherford's experiment showed that an atom is:
ASolid throughout in the standard view
BA continuous wave
CMade of negative gel only
DMostly empty with a tiny dense positive nucleus
Answer & Solution
Correct answer: D. Mostly empty with a tiny dense positive nucleus
1. Most alpha particles passed straight through the gold foil.
2. So most of the atom must be empty space.
3. A few alphas bounced back at large angles.
4. So the positive charge and mass must concentrate in a tiny nucleus.
5. Hence the atom is mostly empty with a small positive nucleus.
