What conclusion was drawn by Rutherford based on Geiger-Marsden.s experiment on scattering of alpha particles ?

Explanation

### Step-by-Step Solution:

1. **Understanding the Geiger-Marsden Experiment**: The Geiger-Marsden experiment, also known as the Rutherford gold foil experiment, involved directing a beam of alpha particles at a very thin foil of gold. The purpose was to observe how these particles scattered after hitting the foil.

2. **Observation of Scattering**: During the experiment, most of the alpha particles passed straight through the foil, while a small fraction were deflected at large angles, and some even bounced back toward the source.

3. **Conclusion about Atomic Structure**:
- **Atom is Mostly Empty Space**: Since most alpha particles passed through without any deflection, Rutherford concluded that atoms are mostly hollow or empty space.
