Select the correct statements from the following.

Step-by-step solution

Statement (1) is incorrect. Atoms with paired electrons and zero nuclear spin (e.g., ⁴₂ He , ¹²₆ C ) have a net magnetic moment of zero. Statement (2) is correct. A proton is a spin- 1/2 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- 1/2 particle and possesses an intrinsic magnetic moment.
