Quantum Mechanics: The Hydrogen Atom 12th April 2008 I. The Hydrogen Atom In this next section, we will tie together the elements of the last several sections to arrive at a complete description of the hydrogen atom. This will culminate in the de nition of the hydrogen-atom orbitals and associated energies.
