In all versions routinely used today in the universities worldwide, helium, the Z = 2 element, is been placed together with other “noble” gases, i.e. It may seem that with the naming of the last superheavy elements in 2016, the history of the formulation of the Periodic Chart is closed, or at least it will rest until the new Period is opened due to a synthesis of a Z > 118 element (Seaborg 1969 Pyykkö 2011). This version of the Table survived in the main didactic room to this day, except for a few elements being given their new IUPAC-recommended names (Francl 2009). Now, the old Group VIII encompasses three modern Groups: 8, 9 and 10. Finally, the freshman years of the 1990s brought another, more subtle, modification: the giant Periodic Table depicted in the Grand Aula of the Chemistry Faculty of the University of Warsaw corresponds to a long version, with noble gases placed in the last Group of the chart, the Group numbering now running from 1 to 18 in Arabic rather than Roman numbers (Fig. Here, the A and B Groups still persisted. On the other hand, the Periodic Table recommended to this author during education in the comprehensive school a decade later was the so-called long version (LPT), with the transition metal elements clearly separated from the main group ones (Fig. Here, noble gases stand out as Group 0, to emphasize lack of room for them in the original Mendeleyev’s formulation this happily coincides with their null (or weak at best) bond-forming ability. This version follows to some extent the early formulation by Mendeleyev, and introduces Group VIII containing Fe, Co, Ni, and their heavier analogues. The traditional depiction of the periodic system, which has been taught to this author in primary school in the 1980s, has been the so-called short version (SPT), with the division to A (main group) and B (transition metal) Group elements (Fig.
