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

The calculated 'spin-only' magnetic moment of Ti2+ (3d2)\text{Ti}^{2+}\ (3d^2) is :

Options

  1. A5.925.92 BM
  2. B3.873.87 BM
  3. C2.842.84 BM
  4. D4.904.90 BM

Correct answer

C. 2.842.84 BM

Step-by-step solution

The atomic number of Ti\text{Ti} is 2222.

Electronic configuration of Ti\text{Ti} is [Ar]3d24s2[\text{Ar}] 3d^2 4s^2.

Electronic configuration of Ti2+\text{Ti}^{2+} is [Ar]3d2[\text{Ar}] 3d^2.

Number of unpaired electrons, n=2n = 2.

Spin-only magnetic moment, μ=n(n+2) BM\mu = \sqrt{n(n+2)} \text{ BM}.

μ=2(2+2)=8≈2.84 BM\mu = \sqrt{2(2+2)} = \sqrt{8} \approx 2.84 \text{ BM}.

Answer: 2.842.84 BM
