Document Summary

Last chem 110 class d1,d4-d7 strong vs weak does not matter. Cr2+ wf ligand forms high spin, sf forms low spin. Crystal field theory cannot explain why each ligand behaves the way it does. Periodic trends atomic radius, ie, en, polarizability, ea. Need to know some of the exceptions. Small so p-orbitals overlap effectively, for multiple pi-bonds. Hydrides salt-like hydrides covalent hydrides metallic hydrides . Be able to tell oxidation state of central atom. Bond energy decreases down group except from f to cl. If you need to alkene gets the lowest number.
