Question

Why only gold foil is used for α-ray scattering experiment?

  1. As it has 1000 atoms in it
  2. As gold is thin and where rays can easily pass.
  3. Scientist wanted to use only gold
  4. Both A and C

hintHint:

Gold is the thinnest metal and is 1000 atoms thick, so it was selected to do an α-ray scattering experiment.

The correct answer is: Both A and C


    • Rutherford used only gold foil for the α-ray scattering experiment .
    • Gold is the metal that is most malleable and can be folded several times.
    • He wanted the thinnest metal and gold is 1000 atoms thick.
    • So he selected gold for his experiment.
