The quantum mechanical approach to atomic orbital theory tells us that electrons exhibit dual character; they behave both as particles and as waves. This behavior is best expressed in terms of wave functions, a term essentially synonymous with orbital. In this chapter, 50 terms and concepts ...

Fundamentals of Molecular Orbital Theory 6.4SUMMARY • nAOs combine to generatenMOs. • the energy of anMOincreases as the number of nodes increases. • the nodes must be symmetrically disposed along the MO. • the interaction of AOs on terminal atoms is considered first and the resulting...
In a complementary approach, the electronic structures of molecules and extended solids can be built up from constituent atoms with use of molecular orbital theory. The orbitals evolve into bands which provide a useful description when the number of atoms is large. To illustrate, consider the inter...
The 2(1,0)n-1P°, 2(1,0)n +3P°, 2(0,1)n+1P°, and 2(0,1)n-3P° intershell Rydberg series of the helium-like ions are investigated in the framework of the modified Atomic Orbital Theory (MAOT). High-lying energy resonances of He and excitation energy of the he- lium-like...

but real behavior is much more complex. Some electron shells resemble spheres, but others look more like dumb bells or other shapes. Technically, an electron can be found anywhere within the atom, but spends most of its time in the region described by an orbital. Electrons can also move bet...
