Which of the following electronic configuration would be associated with the highest magnetic moment ?

Options

  1. A[ Ar ] 3 d 7
  2. B[ Ar ] 3 d 8
  3. C[ Ar ] 3 d 3
  4. D[ Ar ] 3 d 6

Correct answer

D. [ Ar ] 3 d 6

Step-by-step solution

A magnetic moment is a quantity that represents the magnetic strength and orientation of a magnet or any other object that produces a magnetic field. More precisely, a magnetic moment refers to a magnetic dipole moment, the component of the magnetic moment that can be represented by a magnetic dipole. The greater the number of unpaired electrons, the higher will be the magnetic moment.
