The magneit moment of a transitio metal ...

The magneit moment of a transitio metal is ` sqrt(15)` B.M . Fin dout the mubner of unpaired electrons in it .

Text Solution

Verified by Experts

The correct Answer is:
3
`:.` Magetic moment `= sqrt(n( n + 2 )) B.M`.
(wheree (n) is unpaired electron )
` sqrt(15) = sqrt(n(n + 20)) rArr n = 3` .
