Atomic models energy-level diagrams

It is also useful to consider the bonding among the carbon atoms in diamond in terms of the MO model. Energy-level diagrams for diamond and a typical metal are given in Fig. 16.27. Recall that the conductivity of metals can be explained by postulating that electrons are excited from filled levels...

Energy Configuration Diagram. This model, based on the energy level diagrams of atoms and molecules, is applicable to luminescence processes in which excitation and emission take place at the same luminescence center. 

We can combine this spin concept and our orbital model to build atoms electron by electron. This is done by using what is called an energy-level diagram, shown in Figure 5.22. Each box represents an orbital, each electron is represented by an arrow, and two electrons spinning in opposite directions in the same orbital are shown as two arrows pointing in opposite directions. 

Atomic Systems. Many atomic species may be modeled as three-level systems. Figure 2 illustrates the energy level diagram for sodium. Other alkali and alkaline metals behave in a similar manner. 

In terms of this model, two effective pairs around an atom will always require sp hybridization of that atom. The sp orbitals of carbon in carbon dioxide are shown in Fig. 14.15, and the corresponding orbital energy-level diagram for their formation is given in Fig. 14.16. The sp hybrid orbitals are used to form the a bonds between carbon and the oxygen atoms. Note that two 2p orbitals remain unchanged on the sp hybridized carbon. They are used to form the it bonds to the oxygen atoms. 

The Bohr model thus predicts a discrete energy-level diagram for the one-electron atom (Figs. 4.12 and 4.13). The gronnd state is identified by n = 1, and the excited states have higher values of n (see Fig. 4.12). 

Model 3 The Energy Level Diagram of Another Hypothetical Atom. 

Most textbooks on elementary chemistry describe a simple, but not infallible, model for prediction of the ground state electron configuration of the elements. The model has two components. The first is a schematic orbital energy level diagram for atoms which indicates that orbital energies increase in the order...
