Which of the following statements you think is wrong regarding α...
Incorrect Statement Explanation:

Thickness of the gold foil:
The statement that the thickness of the gold foil is about 100μm is incorrect. In the actual experiment conducted by Ernest Rutherford, the gold foil used was approximately 8.6 x 10^-6 cm or 0.000086 mm thick. This ultra-thin foil allowed for the observation of the scattering effect of alpha particles.

Correct Information:
The correct thickness of the gold foil used in the experiment is crucial as it directly affects the scattering pattern of alpha particles. A thicker foil would not have allowed the observation of the small deflections that led to the discovery of the nucleus.

Key Points:
- The gold foil used in the experiment was extremely thin, approximately 0.000086 mm thick.
- The thinness of the foil was essential in observing the deflection of alpha particles.
- Thicker foils would not have provided the same level of precision in studying the scattering effect.
By correcting this statement and understanding the significance of the foil's thickness in the experiment, we can appreciate the meticulous design and execution of Rutherford's groundbreaking experiment.
