An Ionic Bonding Model - Introducing Crystal Field Theory

1 An Ionic Bonding Model - Introducing Crystal Field Theory 

What we are doing in taking this approach to developing a model is mixing a purely ionic model with an atomic orbital model. The valence orbitals of the central atom are assumed to be influenced by the close approach of the ligands acting simply as points of negative 

The concept of crystal field influences applied for purely illustrative purposes to a set of p orbitals. The directional field here results from imposing a specific interaction along the z axis alone. 

Crystal field influences for a set of d orbitals in an octahedral field. 

Notably, this order is just about independent of metal ion in any oxidation state or even adopting any common geometry.
