Periodic patterns: the Group (n) and Group (n + 10) linkage

Abstract

The early Periodic Tables displayed an 8-Group system. Though we now use an 18-Group array, the old versions were based on evidence of similarities between what we now label as Group (n) and the corresponding Group (n + 10). As part of a series on patterns in the Periodic Table, in this contribution, these similarities are explored for the first time in a systematic manner. Pourbaix (Eh–pH) diagrams have been found particularly useful in this context.

Notes

Acknowledgments

An anonymous referee is thanked for helpful comments which led to a significant improvement of the manuscript. In this study, the series of new consistent Pourbaix (Eh–pH) diagrams in The Aqueous Chemistry of the Elements by Schweizer and Pesterfield (2010) was a useful source of comparative information. For details on specific compounds, Patnaik’s Handbook of Inorganic Chemicals (2003) and Greenwood and Earnshaw’s Chemistry of the Elements (1997) were helpful.
