Rutherford's `alpha` particle scattering experiment eventually led to the conclusion that

Options

A. Mass and energy are related
B. Electrons occupy space arround the nucleus
C. Neutrons are buried deep in the nucleus
D. The point of impact with matter can be precise determined

Explanation

To solve the question regarding Rutherford's alpha particle scattering experiment, we will analyze the experiment's findings and the conclusions drawn from it step by step.

### Step-by-Step Solution:

1. **Understanding the Experiment**:
- Rutherford conducted an experiment where a beam of alpha particles was directed at a very thin foil of gold.

2. **Observations**:
- Most of the alpha particles passed straight through the gold foil without any deflection.
- A small fraction of the alpha particles were deflected at large angles, and some even bounced back.

3. **Conclusion from Observations**:
- The fact that most alpha particles passed through indicates that atoms are mostly empty space.
- The deflections suggest that there is a small, dense, positively charged center within the atom, which we now know as the nucleus.

4. **Structure of the Atom**:
- From these observations, it was concluded that the atom consists of a tiny nucleus at its center, surrounded by electrons that occupy the space around the nucleus.

5. **Evaluating the Options**:
- **Option 1**: "Mass and energy are related" - This is incorrect as it relates to Einstein's theory, not Rutherford's findings.
- **Option 2**: "Electron occupies space around nucleus" - This is correct as it aligns with the conclusion of the experiment.
- **Option 3**: "Neutrons are buried deep in nucleus" - Incorrect, as Rutherford did not address neutrons in his experiment.
- **Option 4**: "The point of impact with matter can be precisely determined" - Incorrect, as this relates to Heisenberg's uncertainty principle.

6. **Final Conclusion**:
- The only correct conclusion from Rutherford's alpha particle scattering experiment is that electrons occupy space around the nucleus.

### Final Answer:
The conclusion from Rutherford's alpha particle scattering experiment is that electrons occupy space around the nucleus.
