The bivalent metalion having maximum paramagnetic behavior among the first transition series element is

Answer»

`Mn^(2+)`
`Cu^(2+)`
`SC^(2+)`
`Cu^(+)`

Solution : `Mn^(2+)(3d^(5)4s^(0))rightarrow5` UNPAIRED electrons
`CU^(2+)(3d^(9)4s^(0))rightarrow1` unpaired electron
`Sc^(2)(3d^(9)4S^(0))rightarrow` unpaired electron
`Cu^(+)(3d^(10)4S^(0))rightarrow0`unpaired electron
Hence , `Mn^(2+)` has MAXIMUM number of unpaired electrons THUS , it shows maximum paramagnetic behaviour
