Find spin only moment of `Ti^(3+),V^(2+) and Sc^(3+)`

The spin only magnetic moments (in BM) for free Ti^(3+), V^(2+) and Sc^(3+) ions respectively are (At.No. Sc : 21, Ti : 22, V : 23)

Calculate spin only moment of given ions (i) Cu^(2+) (ii) Cr^(2+) (iii) Fe^(3+) (iv) Ni^(2+)

The spin only magnetic moment of Fe^(2+) ion (in BM) is approximately

Assertion: The spin only magnetic moment of Sc^(3+) is 1.73 BM. Reason: The spin only magnetic momentum in (BM) is equal to sqrt(n(n+2)) .
