Question

Read the following statements and choose the correct alternative.
Statement I : Aluminium fool cannot bebe used in $\alpha$-particle - particle scattering experiment.
Statement II : Aluminium is a highly malleable metal.

• A. Both statement are true and statement II is a correct reason of Statement I.
• B. Both statement are true and statement II is a not correct reason of Statement I.
• C. Statement I is true and statement II is false
• D. Statement II is true and statement I is false

Answer 1

The correct option is C Statement I is true and statement II is false

• If Aluminium foil was used the,the scattering angles would have changed, but the qualitative results would also change: the reason Rutherford chose gold was because it is EXTREMELY malleable. One can stretch gold foil until it is only a few atoms thick in places, which is not possible with aluminum.
  
• Hence option C is correct answer.
