Question

A d-block element has total spin value of +3. Then, the spin only magnetic moment of the element is approximately:

• A. 2.83 B.M.
• B. 3.87 B.M.
• C. 5.9 B.M.
• D. 6.93 B.M.

Answer 1

Answer: (D)

6.93 B.M.

A d-block element has a total spin value of +3.

Then, the total spin $=3\Rightarrow \frac{n}{2}=3\Rightarrow n=6$

i.e., magnetic moment $=\sqrt{n(n+2)}=\sqrt{6(6+2)}=\sqrt{48}=6.93$ B.M.

Option D is correct.
