Atoms and Quantum Mechanics

When dealing with molecular physics, it is best to start by giving a solid basis on its foundation. And the foundations of molecules are atoms. The Schroedinger equation for atoms is only analytically solvable for the hydrogen atom or hydrogen like ions, i.e., systems with exactly one electron. Approximations can be used to solve any other atom and the conclusion is that the physical way of describing electrons in any atom is essentially the same.
