A Proposal for A New Periodic Table of The Elements

Ramdane Quahes
From USTHB University, 12 Baulevard Amirouche, BORDJ EL KIFFAN, Algiers, Algeria.

A new periodic table is proposed consisting of 8 periods instead of 7. A period of rank k correspond to the completion of shells and sub-shells according to the relationship n+1= k between quantic numbers. The new proposed chart eliminates the defects of the present table and, hence, has didactic advantages.

Keywords: Periodic table, element, shell, sub-shell
