The calculated 'spin-only' magnetic moment of Ti ²⁺ (3d^2) is :

Options

  1. A5.92 BM
  2. B3.87 BM
  3. C2.84 BM
  4. D4.90 BM

Correct answer

C. 2.84 BM

Step-by-step solution

The atomic number of Ti is 22 . Electronic configuration of Ti is [ Ar ] 3d^2 4s^2 . Electronic configuration of Ti ²⁺ is [ Ar ] 3d^2 . Number of unpaired electrons, n = 2 . Spin-only magnetic moment, = n(n+2) BM . = 2(2+2) = 8 2.84 BM . Answer: 2.84 BM
