Question

Magnetic moment of a divalent ion in aqueous solution of an element with atomic number 25 is:

• A. 2.84 BM
• B. 3.87 BM
• C. 4.90 BM
• D. 5.92 BM

Answer 1

Answer: (D)

5.92 BM

Answer 2

The atomic number $25$ corresponds to the element Manganese $(Mn)$.
The magnetic moment of a divalent ion in aqueous solution of Mn with atomic number $25$ is typically around $5.92$ Bohr magnetons $(BM).$

Therefore, the correct option is (D): $5.92$ BM.
