Detailed Solution for Coordination - Organometallics - Bioinorganic - Question 43

The atomic number of nickel is 28. Thus, it has 8 electrons in 3d orbital. Here, it is in +2 oxidation state which means its two electrons of its electron from 4s orbital have been removed and the 8 electrons of 3d orbital remain untouched.

Now, F- is a weak field ligand and hence does not pair the electrons in 3d orbital. This means there are 2 unpaired electrons left in 3d orbital. Hence,  has 2 unpaired electrons.
