The magnetic nature of elements depends onthe presence of unpaired electrons. Identify theconfiguration of transition elements whichshows highest magnetic moment?

Options

  1. A( 3 ~d ⁷ )
  2. B( 3 d⁵ )
  3. C( 3 d⁸ )
  4. D( 3 d² )

Correct answer

B. ( 3 d⁵ )

Step-by-step solution

For the given electronic configurations, the spin only magnetic moment is shown below: Therefore, ( 3 d⁵ ) configuration have highest magnetic moment.
