In Rutherford's \( \alpha \) -rays scattering experiment, gold foils are used because of
- A. high malleability
- B. ductility
- C. high melting point
- D. high ionisation energy
Step-by-step solution
In Rutherford's alpha-particle scattering experiment, a thin gold foil is used because gold is highly malleable, allowing it to be hammered into extremely thin sheets. This ensures that alpha particles can pass through with minimal scattering from multiple atoms, enabling the observation of single scattering events. High malleability is the key property for this purpose; ductility, high melting point, and high ionization energy are not directly relevant.
