Abstract

This presents a new periodic chart with 18 columns but no interruptions of atomic numbers at Lanthanum or Actinum, and no de-emphasis of elements 57-71 or 89-103 by seeming to make footnotes of them. It shows some elements more than once in order to illuminate multiple relationships in chemical behavior.
