Transition elements show magnetic moment due to spin and orbital motion of electrons. Which of the following metallic ions have almost same spin only magnetic moment?

Answer»

`Co^(2+)`
`CR^(2+)`
`MN^(2+)`
`Cr^(3+)`

Solution :Both `Co^(2) and Cr^(3+)` have 3 unpaired electrons and so both have ALMOST same spin only MAGNETIC moment.
