Question

Maximum magnetic moment shown by:

• A. Mn\(^{2+} \)
• B. Fe\(^{2+} \)
• C. Cr\(^{3+} \)
• D. Ni\(^{2+} \)

Hint:

To determine the maximum magnetic moment, count the number of unpaired electrons in the ion. The more unpaired electrons, the greater the magnetic moment.

Answer 1

The Correct Option is A

The magnetic moment of an ion depends on the number of unpaired electrons in the d-orbitals. The Mn\(^{2+}\) ion has 5 unpaired electrons, leading to the maximum possible magnetic moment.
