Answer 2

The complete question is given below:

Which of the following is an incorrect statement in reference with observation in Rutherford’s α-particle scattering experiment?​

(a) Some of the α-particles rebound after hitting the gold foil  

(b) Some of the particles deflected from their path

(c) Some of the particles not pass through the gold foil  

(d) Most of the particles pass straight through the gold foil

The correct answer to this question is option (c) Some of the particles not pass through the gold foil  .

Explanation:

• Rutherford used a very thin gold foil for his experiment.

• A very small number of α-particles hit the positively charged nuclei and hence rebounded.

• Some particles were deflected from their path as they were repelled by the nuclei when they passed close to it.

• As most of the space on the foil was not occupied by nuclei, so a large number of α-particles passed without any deflection.

• The only wrong statement is (c), as we cannot cite any reasons why a particle would not be able to pass through such a thin foil. Rutherford has also not observed anything like this in his experiment.
