A Proposal of A New Version for The Periodic Table of The Elements

In spite of its usefulness, the present version of the Periodic Table of the elements shows serious defects from a didactic point of view. A through analysis of the periodicity of the physical properties of the elements - and especially recent data concerning electron affinity - shows cleanly that the best element for ending each period should be an alkaline earth metal. Thus a new chart is built. It consists of eight periods, separates the four blocks and provides a satisfactory picture of the electron configurations.

Keywords: Periodic table, electron configurations, elements
