Abstract

Schrödinger’s equation, as we have seen in chapter 10, gives the same energies for the hydrogen atom as the Bohr model. It is only when we consider many electron systems that new effects are manifest, the most important being those due to the Pauli exclusion principle which is fundamental to an understanding of the building up of the periodic table. In this chapter, we shall first consider the ground state of a two-electron system, namely the helium atom and then go on to examine a few excited states in order to understand the basic principles of the study of atomic structure.
