Periodic Table formulations from the year 1867:

1867   Hinrichs' Programme of Atomechanics


1867

Hinrichs' Programme of Atomechanics

Gustavus Detlef Hinrichs' spiral "Programme of Atomechanics". Programm der Atomechanik oder die Chemie eine Mechanik de Pantome, Augustus Hageboek, Iowa City, IA (1867).

Hinrichs' system is based on the relationship of what he called: "pantogens, with its atoms called panatoms, which explains the numerical relations of atomic weights and gives a simple classification of the elements."

This classification system culminated in 1867 in his spiral periodic table, which better clarified the groupings of elements. Hinrichs' classification, while distinctly different from the other periodic tables of this period, "seems to capture many of the primary periodicity relationships seen in the modern periodic table... it is not cluttered by attempts to show secondary kinship relationships." (Scerri)
