Oxygen energy level diagram

Figure 1 is an energy level diagram showing a proposed model for the band structure of zinc oxide. The valence band and conduction band are shown separated by a forbidden gap. Two levels which correspond to the trapping of two electrons by the interstitial zinc are indicated in the forbidden gap. Surface levels associated with adsorbed oxygen are shown.

The energy level diagram for CO2 is shown in Fig. 3.4.6. Note that the oxygen 2p orbitals are more stable than their corresponding orbitals on carbon. The 16 valence electrons in CO2 occupy the orbitals as shown in Fig. 3.4.6 and the ground configuration for CO2 is... 

Figure 6.4 Energy level diagram for 3d orbitals of transition metal ions located in six-coordinated sites of different symmetries, (a) Octahedral (b) tetragonal (elongated along the tetrad axis) (c) trigonal (compressed along the triad axis) (d) monoclinic (cf. fig. 6.4). The average metal-oxygen distances are assumed to be the same for each site.

The procedure for calculating energy level diagrams by the self-consistent field Xa scattered wave (SCF-Xa-SW) method is as follows (Sherman, 1984, 1991). An octahedral cluster such as [FeO6]10 is partitioned into a set of (overlapping) spheres centred about divalent iron and each oxygen atom, and these are surrounded by an outer sphere. Within each atomic sphere the one-electron Schrodinger equation... 

Figure 11.6 Molecular orbital energy level diagrams computed for iron octahedrally coordinated to oxygen. Left divalent iron in the [Fe06]-1° cluster (based on Sherman, 1991) right trivalent iron in the [Fe06]-9 cluster (from Sherman, 1985a). Orbital energies have been scaled relative to zero for the non-bonding 6rlu level.

Atomic orbital energy level diagrams. To simplify these diagrams, the orbitals are shown at the same energies for different atoms. Actually, the energy of an orbital decreases as the number of protons in the atom increases.Thus the Ip orbitals of fluorine are lower in energy than the Ip orbitals of oxygen. 

Hund s rule states that the electrons within a given subshell remain as unpaired as possible. Moreover, if there are two or more unpaired electrons in a given subshell, they all must occupy different orbitals and have the same electron spin (all arrows representing unpaired electrons in a subshell point up or all point down). The energy level diagrams for the carbon, nitrogen, and oxygen atoms illustrate these rules ... 

The energy level diagrams show one unpaired electron in a fluorine atom, two in an oxygen atom, and one in a boron atom.
