The magnetic nature of elements depends on the presence of unpaired electrons. Identify the configuration of transition element, which shows highest magmetic moment.

Options

  1. A3 d^7
  2. B3 d^5
  3. C3 d^8
  4. D3 d^2

Correct answer

B. 3 d^5

Step-by-step solution

3 d^5 has maximum unpaired electrons (5 e⁻ ) , so it has magnetic moment.
