The formula used to calculate the spin-only magnetic moment can be written in two forms; the first based on the number of unpaired electrons, n, and the second based on the electron spin quantum number, S . Since for each unpaired electron, n=1 and S=1/2 then the two formulae are clearly related and the answer obtained must be identical.
- if unpaired electron is present in transition elements then it should be paramagnetic
- if no unpaired electron is present in transition elements then it should be diamagnetic
- if unpaired electron is present in transition elements then it should be colour and Colour of transition metal ions are due to absorption of some wavelength in UV Light
- if no unpaired electron is present in transition elements then it should be colorless
