in the atom. It was Sommerfeld's theory that first provided an actual starting-point for discussion of the structure of the atom on the basis of spectra. Som merfeld thus brought about an important extension and refinement of the quantum theory of the atomic structure. On the basis of the Sommerfeld theory, the old quantum theory of spectra was ...

shows a general periodic table that kids can explore to see the s, p, d, f blocks, generate graphs of atomic mass, electronegativity, year of discovery vs. atomic number, and much more. This is VERY broad, and would benefit greatly from some guided questions, but it is a very good site for exploration.

Chapters 7 to 16 discuss the abstract group theory, invariant subgroups, and the general theory of representations. These chapters are mathematical, although much of the material covered should be familiar from an elementary course in quantum theory. Chapters 17 to 23 are specifically concerned with atomic spectra, as is Chapter 25.

We have previously used simple empirical equations to reproduce the literature values of the ionization energies of isoelectronic sequences of up to four electrons which gave very good agreement. We reproduce here a kinetic energy expression with corrections for relativity and Lamb shift effects which give excellent agreement with the literature values.
the atomic lattice, does not occur. The new pairing mechanism is not known, but must arise from features common to the atomic structure of high-temperature superconductors. Their lattices have a layered structure, and also typically constitute a distortion, due to substituted ‘alien’ atoms, of a more highly symmetrical lattice structure.
