### The Energy of Atomic Orbitals

http://physics.nist.gov/PhysRefData/DFTdata/Tables/ptable.html (External link to NIST Atomic total energies and eigenvalues) The energy levels shown in this video are the result of computation based on atomic quantum theory. Notice that the energy scale is logarithmic. Reference: M. Kasha and R. Latter, Phys. Rev., 1955, 99, 510 Trends in the energies of atomic orbial levels are summarized. These trends explain electronegativity and will be used to predict how strongly a pair of orbitals interact.
