explain why magnetic moment of either Ni(II) Td or Co(II) Oh(HS) is higher than the magnetic moment value ,?

Question

question from inorganic chemistry

Answer 1

I'm assuming you mean the Bohr magneton of a single electron? Or the magnetic moment of the neutral atom?

When they are neutral, all of these atoms have electrons with their spins oriented a particular way. Some spins cancel, while others add. The magnetic moment of the neutral atom is the result of all of this adding and subtracting. Now take away some electrons. Depending on which ones you remove, the balance will shift. This is what's going on.
