MAGNETIC MOMENT OF DIVALENT ION IN AQUEOUS SOLUTION ATOMIC NO. 25

Question

Calculate the magnetic moment of a divalent ion in aqueous solution if its atomic number is 25?

Answer 1

The atomic number is 25. The metal is manganese with valence shell ,electronic configuration  3d⁵ 4s² . The divalent ion  Mn²⁺  has valence shell  electronic configuration  3d⁵ 4s⁰ . It contains five unpaired electrons.

n = 5  

It's spin only magnetic moment is
