The calculated 'spin-only' magnetic moment of Ti ²⁺ (3d^2) is :
Options
- A5.92 BM
- B3.87 BM
- C2.84 BM
- 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
