Question

Which ion co+3 cr+3 ni+3 cu+1 is having maximum magnetic moment?

Answer 1

Explanation:

co 3+ has maximum magnetic moment.

You can do this by looking at the number of unpaired electrons.

In this case Co 3+ it has 4 unpaired electrons as it has 3d6 con figuration

In Cr3+ no of unpaired electrons are 3 .

In Ni3+ also unpaired electrons are 3 as it has 3d7 configuration

In Cu1+ no unpaired electron because of 3d10 configuration.
