Question
The magnetic nature of elements depends on the presence of unpaired electrons. Identify the configuration of transition element, which shows highest magnetic moment.
Options
3d7
3d5
3d8
3d2

Solution
3d5
Explanation:
The greater the number of unpaired electron, the higher will be its value of magnetic moment. Since, 3d5 has 5 unpaired electrons hence highest magnetic moment.
`mu = sqrt(5(5 + 2))`
= `sqrt(35)`
= 5.95 BM
