    The First Metals in Mendeleiev’s Table: Further Arguments to Place He Above Ne and Not Above Be. [REVIEW]Alejandro Ramírez-Solís & Octavio Novaro - 2014 - Foundations of Chemistry 16 (2):87-91.
    In a recent paper in this Journal, one of us argued against placing He above Be in Mendeleiev’s system of the elements. In it the goal was to dispute the notion that in Mendeleiev’s system of the elements the location of He should in fact lie above Be, which has a very similar electronic configuration, rather than above the noble gas column. That paper was based on rather old, Hartree–Fock limit studies on the strikingly limited non-additive contributions in the He3 (...)

    On the Rightful Place for He Within the Periodic Table.Octavio Novaro - 2008 - Foundations of Chemistry 10 (1):3-12.
    Many different arguments have been put forward in order to assign the best place for a given element within Mendeleev's Table: its spectroscopy, its chemical activity, the crystalline structure of its solid state, etc. We here propose another criterion; the nature of the few body corrections to the pairwise additive energy. This argument is used here to address a question often brought forward by Eric Scerri in Foundations of Chemistry, namely the rightful place of helium; either above the column of (...)

    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 - 2014 - 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 (...)

    Activity of Closed D-Shells in Noble Metal Atoms.Octavio Novaro - 2004 - Foundations of Chemistry 7 (3):241-268.
    The Periodic Table has the column of the noble gas atoms (He, Ne, Ar, Kr, Xe, Rn) as one of its main pillars. Indeed the inert chemical nature of their closed shell structure is so striking that it is sometimes extended to all such structures. Is it true however that any closed shell, say a closed d-subshell will denote a lack of chemical activity? Take the noble metals for instance, so renowned for their catalytic capacity. Platinum has 10 electrons in (...)
