MCQ
In Rutherford's α-rays scattering experiment, gold foils are used because of ___________?
  • A
    High malleability
  • B
    Ductility
  • C
    High melting point
  • D
    High ionisation energy
✓

Answer

  1. High malleability

Explanation:

Malleability is the material's ability to form thin sheets.

In Rutherford's ray scattering experiment, gold foil is used because of its high malleability.

Very thin gold foil is used in the experiment and gold is capable of being rolled into extremely thin foils.
