Z=27 implies element is Co.Co²+ carries 7 electrons in d orbital. For aq solution H2O is the ligand which is weak field ligand. So metal will tend to form tetrahedral structure, carrying 3 unpaired electrons in t2g.So spin only magnetic moment would be √ (3 (3+2)) = √15 = 3.87 mani sharma 24 Points 4 years ago. Magnetic moment has contributions from spin and orbital angular momentum. A non-spherical environment may lead to quenching of the contribution from orbital angular momentum. However, the spin-only magnetic moment survives in all cases and is related to the total number of unpaired electrons. μ eff = μ s.o = 2√S(S+1) = √n(n+2) BM.

Co2+and Co3+, Fe2+above) • non-degenerate ground states do not have a contribution from L so values close to the spin only moment are usually found (eg. Ni2+) (b) contributions from spin-orbit coupling • Spin-orbit coupling means that S and L do not operate independently and J states need to be defined. The magnetic susceptibilities of V (bipy) 3 (ClO 4) 2, K 3 Cr(CN) 6, and K 2 MnCl 6 have been measured in the temperature range of liquid‐nitrogen to room temperature.

The formula used to calculate the spin-only magnetic moment can be written in two forms; the first based on the number of unpaired electrons, n, and the second based on the total electron spin quantum number, S. Since for each unpaired electron, n=1 and S=1/2 then the two formulae are clearly related and the answer obtained must be identical. The formula to calculate the magnetic moment is: μ = n ( n + 2) B.M. The Electronic configuration of Co in +2 oxidation state Co+2 = A r 3d74S0 Box diagram for valence electrons is Hence the number of unpaired electrons is 1, ie n=1. By substituting the value of n in the formula to calculate magnetic moment. Isotopes that have a magnetic moment (and can thus be imaged by an MRI) are ones with an ODD atomic mass number. This is because an odd atomic mass number indicates an odd number of neutrons + protons, resulting in the nucleus having a nonzero spin and magnetic moment, thus becoming affected when placed in a magnetic field.
