A useful periodic table of the elements provides a number of important facts for its user: valence, metallic vs non-metallic compound formation and atomic weight being some of the more valuable. The current popular version has proven quite adequate in this regard for many chemists. A stubborn adherence to the stoic spdf-quantum-theory model, however, creates problems. Thus, this perspective requires that H be placed over Li and/or F even though it has little or no chemical similarity to either of them. This view of the electron structure of atoms also requires a number of “rules” and “hybridizations” to explain even the simplest aspects surrounding the electron structure and chemical bonding; mathematical orthogonality between periodic levels is a sham; and increasingly weirder shaped orbitals are needed to make the math fit the stoic spdf model. Transition and rare-earth/lanthanide series appear without physical rationale. In light of all these spdf-associated problems, the arrangement and behavior of the elements in the periodic table is addressed in this document according to the dynamic MCAS electron orbital model.
