Question

the number of species which are dimagnetic amongest the following :
`Fe^(2+),Fe^(4+),Mn^(2+),Cr^(3+)`
`Ni^(2+),Cr^(+6),Mn^(+7),V^(3+),Sc^(3+)`

Answer 1

Correct Answer - 3
`{:(Fe^(2+),[Ar]3d^(6),Cr^(6+)[Ar]-("Dimagetic ")),(Fe^(4+),[Ar]3d^(4),Mn^(+7)[Ar]-("Diamagentic")),(Mn^(2+),[Ar]3d^(5),V^(3+)[Ar]-3d^(2)),(Cr^(3+),[Ar]3d^(3),Sc^(3+)[Ar]-("Diamagnetic ")),(Ni^(2+),[Ar]3d^(3),):}`
