Dear Student
atomic no = 26
 
The divalent ion in aqueous solution with atomic number 25 will be having a d6 configuration
i.e. it will be having 4 unpaired electrons
Magnetic moment can be calculated as follows:
 
\mu= \sqrt4(4+2)
\mu= \sqrt26
\mu= 5.099
\mu= 5.1 BM

HERE atomic number z=26 means it  is ferrum. it has configuration of d6 s2 on losing 2 electrons that forms d6 configuration. in this configuartion we have 4 unpaired electrons such that the magnetic moment is calculated by
root over n(n+2) i.e.root of 4(4+2)=root 24=4.898 is the magenetic of given ion.
