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

The Correct Option is D

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.
