Question

III. COORDINATION CHEMISTRY: BONDING CONCEPTS 12. (8) Use the VB approach to provide a model that is consistent with the following observations: the [CoFo]-ion is paramagnetic, while the [CO(NH3).] ion is diamagnetic. Be sure to indicate which atomic orbitals on the Co ion you are using for hybridization in each case. led ad

simple explanation and a numerical order of steps to achieve the answer please
