Rectangular Array Model of Chemical Elements

Dr. Laith H . M . Al-ossmi, Rectangular Array Model of Chemical Elements https://www.academia.edu/119516234/Rectangular_Array_Model_of_Chemical_Elements

Abstract: This paper introduces a novel graphical representation of the periodic table, termed the "Rectangular Array Model". This innovative representation adheres to the group numbering recommendations provided by the International Union of Pure and Applied Chemistry (IUPAC). The rectangular array model arranges the known chemical elements (118 elements) according to their similarities in chemical properties, within 7 horizontal periods and 14 vertical groups. Hydrogen has been relocated to join oxygen within the elements of the first period and group 12. The rectangular array model reattached the position of 30 elements of lanthanides and actinidines into the table body. We respectfully encourage educators across various academic institutions to adopt this new periodic table format in their teaching practices.

Mark Leach the PT database administrator & curator writes:

WARNING: This formulation is NOT contiguous with respect to atomic number (surely, a prerequisite for any periodic table formulation?); it does NOT use IUPAC Group Numbers correctly, even though the abstract states that it does; it does not present electron or orbital structure and neither does it show periodicity in any way.
