Electrons on Atoms and Interaction with Light

Valence Electrons on Atoms and Interaction with Light 

This section describes a model for the behavior of valence electrons on a spherical, symmetric, free atom. The subject is of some use for the inorganic chemist. It adds a basic regularity to the periodic table and it is necessary for the assignment of spectroscopic absorption and emission bands of atoms and molecules. It is also the basis for discussions of electrons in chemical bonds.
