Arrange the following metal complex/compounds in the increasing order of spin only magnetic moment. Presume all the three, high spin system.(Atomic numbers Ce=58, Gd=64 and Eu=63)a) NH42CeNO36     b) GdNO33    c) EuNO33

a) ln NH42CeNO36 Ce oxidation state is +4EC of Ce+4⋅[xe]6s05d04f0, therefore n=0, hence magnetic moment =0EC of Gd+3⋅[Xe]6s05d04f7 , therefore n=7, hence magnetic moment =7.93EC of Eu+3⋅[xe]6s05d04f6, therefore n=6, hence magnetic moment =6.92
