The ‘‘spin-only’’ magnetic moment [in units of Bohr magneton, ( μ B ) of Ni 2+ in aqueous solution would be (atomic number of Ni = 28)
Text Solution
Verified by ExpertsThe correct answer is:
A
Valence shell electron configuration of 28 Ni 2+ is 3d 8 4s 0
Or 
So, number of unpaired electrons (n) = 2
∴ μ =
