Options
- A. 5.92 BM
- B. 3.87 BM
- C. 2.84 BM
- D. 4.90 BM
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
