Question
Why only gold foil is used for α-ray scattering experiment?
- As it has 1000 atoms in it
- As gold is thin and where rays can easily pass.
- Scientist wanted to use only gold
- Both A and C
Hint:
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.
