The spin only magnetic moments (in BM) for free Ti³⁺, V²⁺ and Sc³⁺ ions respectively are :

(At.No. Sc : 21, Ti : 22, V : 23)

Multiple Choice Options

A 3.87, 1.73, 0
B 1.73, 3.87, 0
C 1.73, 0, 3.87
D 0, 3.87, 1.73

Step-by-Step Verified Solution

\mu = \sqrt {n(n + 2)} BM

\begin{matrix} T i^{+ 3} = [A r] 3 d^{1} & n = 1 & μ = 1.73 B M \\ V^{+ 2} = [A r] 3 d^{3} & n = 3 & μ = 3.87 B M \\ S c^{+ 3} = [A r] 3 d^{0} 4 s^{0} & n = 0 & μ = 0 \end{matrix}
