Select the correct statements from the following.

Select the correct statements from the following.

Options

  1. AAll atoms possess a magnetic moment.
  2. BAll protons possess a magnetic moment.
  3. CAll nuclei possess a magnetic moment.
  4. DAll electrons possess a magnetic moment.

Correct answer

D. All electrons possess a magnetic moment.

Step-by-step solution

Statement (1) is incorrect. Atoms with paired electrons and zero nuclear spin (e.g., ^{4}_{2}\text{He},612C, ^{12}_{6}\text{C}) have a net magnetic moment of zero.

Statement (2) is correct. A proton is a spin-1/21/2 particle and possesses an intrinsic magnetic moment.

Statement (3) is incorrect. Nuclei with an even number of protons and an even number of neutrons (even-even nuclei) have zero nuclear spin and zero magnetic moment.

Statement (4) is correct. An electron is a spin-1/21/2 particle and possesses an intrinsic magnetic moment.
