Question

Assertion: Aluminium foil cannot be used in $\alpha$ - particle scattering experiment
Reason: Aluminium is highly malleable metal.

• A. Both Assertion and Reason are correct and Reason is the correct explanation of Assertion.
• B. Both Assertion and Reason are correct, but Reason is not the correct explanation of Assertion.
• C. Assertion is correct but Reason is incorrect.
• D. Assertion is incorrect but Reason is correct.

Answer 1

The correct option is B

Both Assertion and Reason are correct, but Reason is not the correct explanation of Assertion.

Both A and R are correct statement. But gold is most malleable, so it was used in particle scattering experiment as a very thin sheet of gold with around a 1000 molecules was needed to record the scattering of the alpha particles.
