How to calculate magnetic moment of transition metal

 



  • To calculate magnetic moment of transition metal. First we need a formula.... 
  • To calculating magnetic moment of transition metal formula is √n(n+2)
  • For example- Cr3+   we know Chromium metal is a d block element and it's have 5 electron in d orbital and one electron in s orbital.. It's electronic configuration  is 1s2 2s2 2p6 3s2 3p6 3d5 4s1

But in oxidation state +3 is 1s2 2s2 2p6 3s2 3p6 3d3 

When we put formula,  √n(n+2)

n=no of Valence electron

In chromium three valence electron is present

n=3

=√3(3+2)=√15
