![]() If you have any questions still, and if this is still confusing, just ask. Rare-earth fluorine-containing molybdates of the Ln5Mo3O16+ oxygenelectron conductor family with the LiLa4Mo3O15F composition were synthesized for the. of the participating frontier molecular orbitals (FMO) i.e., HOMO and LUMO. To modify the diagram for #"O"_2^(-)#, simply add one electron to the highest-energy MO. HSAB Principle - Pearsons Hard Soft Acid Base Theory Stability of metal.To modify the diagram for #"O"_2^(+)#, simply remove one of the highest-energy electrons.Each oxygen atom contributes six electrons to O2 molecule from. So, when we combine what we see here into the full diagram, we first get:Īnd then when we fill the MOs with the #16# total electrons contributed from both oxygens, according to the same three rules and principles defined for the AO diagram, we get: The atomic number of Oxygen is eight and electronic configuration is, 1s2 2s2 2px2 2py1 2pz1. "Normal" means it is just like what I'm showing you here.

When we consider these interactions, we'll see the #ns# (sigma, head-on) interactions:Īnd the slightly more complicated #np# (pi, sidelong, and sigma, head-on) interactions: The former is stabilized (lower in energy) relative to the AOs, and the latter is destabilized (higher in energy) relative to the AOs. Next, recall that there exist bonding ( #sigma#, #pi#, etc) and antibonding ( #sigma^"*"#, #pi^"*"#, etc) orbitals. That means with #\mathbf(10)# AOs in, you get #\mathbf(10)# MOs out- #5# per oxygen. These interactions generate what are called molecular orbitals, and they will conserve the number of orbitals. So, the #2s# interacts with the #2s#, and the #2p# interacts with the #2p#, etc. That means which ones can overlap to create an effective bond.įor a homonuclear diatomic molecule like #"O"_2#, this is simple just choose the orbitals that are alike in look and energy. Next, consider which orbitals can interact with each other. If you are unsure about any of these rules or principles, you should ask for further clarification, as I assume you already are familiar with these.Īt this point, we have the AO diagram as follows for both oxygen atoms:
