The higher number of unpaired electrons are in

Valence bond theory successfully explains the magnetic behaviour of complexes. The substances which contains unpaired electrons. and paramagnetic character increases as the mumber of unpaired electrons increases. Magnetic moment of a complex can be determined experimentally and by using formula sqrt(n(n+2)) and we can determine the number of unpaired electrons in it. This information is important in writing the electronic structure of complex which in turm is also useful in deciding the geometry of complex. The magnetic moments (spin only) of [NiCl_(4)]^(2-) and [Ni(CN)_(4)]^(2-) are:

The substances which contain species with unpaired electrons in their orbitals behave as paramagnetic sustances. Such substances are weakly attracted by the magnetic field. The paramagnetism is expressed in terms of magnetic moment. The magnetic moment is related to the number of unpaired electrons according tot he following relation: Magnetic moment mu=sqrt(n(n+2))BM where n=number of unpaired electrons. BM stands for Bohr magneton, a unit of magnetic moment. 1BM=(eh)/(4pimc)=9.27xx10^(-24)Am^(2) or JT^(-1) Q. Which of the following ions has magnetic moment equal to that of Ti^(3+) ?
