Metal of which foil was used in Rutherted experiment ?

Options

A. Silver
B. Gold
C. platinum
D. Iron

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks for the metal used in the foil during Rutherford's experiment. This experiment was crucial in the development of atomic theory.

2. **Identifying the Experiment**: Rutherford's experiment is commonly known as the gold foil experiment. It involved the scattering of alpha particles to study the structure of the atom.

3. **Selecting the Metal**: In the gold foil experiment, Rutherford used a very thin foil of gold. Gold was chosen specifically because of its unique properties.

4. **Reason for Choosing Gold**: Gold is highly malleable, meaning it can be hammered into extremely thin sheets without breaking. This property was essential for the experiment, as a very thin foil was necessary to allow alpha particles to pass through and scatter.

5. **Conclusion**: Therefore, the metal foil used in Rutherford's experiment was gold.

**Final Answer**: The metal used in the foil for Rutherford's experiment was **gold**.
