  1. On the ‘true position’ of hydrogen in the Periodic Table.Vladimir M. Petruševski & Julijana Cvetković - 2018 - Foundations of Chemistry 20 (3):251-260.
    Several attempts have recently been made to point to ‘the proper place’ for hydrogen in the Periodic Table of the elements. There are altogether five different types of arguments that lead to the following conclusions: hydrogen should be placed in group 1, above lithium; hydrogen should be placed in group 17, above fluorine; hydrogen is to be placed in group 14, above carbon; hydrogen should be positioned above both lithium and fluorine and hydrogen should be treated as a stand-alone element, (...)

  • The first metals in Mendeleiev’s Table: Part II. A new argument against the placement of hydrogen atop the alkali metal column. [REVIEW]Raymundo Hernández & Octavio Novaro - 2013 - Foundations of Chemistry 16 (3):177-180.
    Every so often an experiment trying to give reliable evidence for a metallic hydrogen solid is reported. Such evidence is, however, not too convincing. As Eric Scerri has recently reiterated, “the jury is still out on that issue” . This search stems from the common spectroscopy shared by the hydrogen atom and all the alkali metal atoms, and perhaps is guided by a desire to place hydrogen atop the alkali metals, in Mendeleiev’s Table, reinforced by the fact pointed out by (...)
