For the exam

For the exam you should

be familar with the atomic orbitals and be able to calculate their energies.
be able to explain the Born-Oppenheimer approximation.
be able to write down the many-electron Hamiltonian for any atom.
be able to approximate the many-electron Hamiltonian in terms of a sum of atomic-orbital Hamiltonians.
be able to explain why ignoring the electron-electron interactions makes solving the many-electron problem much easier.
be able to construct an approximate multi-electron wave functions of any atom as antisymmetrized products of atomic orbitals.
be able to explain what the exchange energy is.
be able to evaluate the energy of a trial wavefunction (a guess) in any Hamiltonian.
