Electron configuration magnetic properties

So far we have focused on the reactants—the atoms—in the process of electron loss and gain. Now we focus on the products—the ions. We examine electron configurations, magnetic properties, and ionic radius relative to atomic radius. 

Ions Electron Configurations, Magnetic Properties, Ionic Radii, and Ionization Energy 355... 

Recall that ions are simply atoms (or groups of atoms) that have lost or gained electrons, hi this section, we examine periodic trends in ionic electron configurations, magnetic properties, ionic radii, and ionization energies. 

Use the spectrochemical series to predict the effect of a ligand on the color, electron configuration, and magnetic properties of a d-metal complex (Examples 16.4 and 16.5). 

Since the octahedral and tetrahedral configurations have the same number of unpaired electrons (that is, 2 unpaired electrons), we cannot use magnetic properties to determine whether the ammine complex of nickel(II) is Octahedral or tetrahedral. But we can determine if the complex is square planar, since the square planar complex is diamagnetic with zero unpaired electrons.
