In Rutherford's experiment, generally the thin foil of heavy atoms, such as gold, platinum, etc. have been used to be bombarded by the `alpha`-particles. If the thin foil of light atoms such as aluminium etc. Is used, what difference would be observed form the above results?

Explanation

### Step-by-Step Solution:

1. **Understanding Rutherford's Experiment**:
- Rutherford's experiment involved bombarding a thin foil of heavy atoms (like gold or platinum) with alpha particles. The purpose was to study the structure of the atom, particularly the nucleus.

2. **Characteristics of Heavy Atoms**:
- Heavy atoms have a significant mass and a large nucleus containing a substantial amount of positive charge. This positive charge is due to the presence of protons in the nucleus.
