This form became popular following the publication of Mendeleev's eight-column periodic table in 1871.Īlso shown in this section is a modernized version of the same table. Short Newlands' 1866 table of octaves Mendeleev's 1871 periodic table Modern form of a short eight-group periodic table Tables that defy easy classification are counted as type 8. continuous (circular, spiral, lemniscate, or helical) 6. While the database is a chronological compilation, specific types of periodic tables that can be searched for are spiral and helical 3-dimensional and miscellaneous.įor convenience, periodic tables may be typified as either: 1. In 1999 Mark Leach, a chemist, inaugurated the INTERNET database of Periodic Tables. In 1974 Edward Mazurs, a professor of chemistry, published a survey and analysis of about seven hundred periodic tables that had been published in the preceding one hundred years he recognized short, medium, long, helical, spiral, series tables, and tables not classified. He added that, "unfortunately there also a number of freaks". In 1954, Tomkeieff referred to the three principle types of periodic table as helical, rectilinear, and spiral. To a lesser extent, the more involved two-dimensional arrangements do little toward solving the difficulty, and essentially the only suggestions as to modifications which are truly constructive are those centering in reflection of electronic configurations.Ĭertainly the most useful of these modifications, and at the same time one of the earliest to be proposed, is the so-called long or. Thus the many three-dimensional models, embracing globes, helices, cones, prisms, castles, etc., are interesting but lacking in utility. Geometry does not permit of an arrangement which is sufficiently ideal to serve all the required purposes equally well. Unfortunately, the majority of the tabulations proposed are either unwieldy or utterly worthless, and only a few valuable suggestions have been made. In fact so many modifications have appeared that one is tempted to conclude that practically every author has his own concept of what a workable arrangement must be. The literature is replete with suggested (and discarded) modifications of the M periodic table. In 1952, Moeller expressed disdain as to the many types of periodic table: In 1934, George Quam, a chemistry professor at Long Island University, New York, and Mary Quam, a librarian at the New York Public Library compiled and published a bibliography of 133 periodic tables using a five-fold typology: I. His objection was that he could not express this function mathematically." Typology On spiral periodic tables, "Mendeleev.steadfastly refused to depict the system as. It appeared to him that the latter (three-dimensional) form would be the most natural approach but that "attempts at such a construction have not led to any real results". Since Dimitri Mendeleev formulated the periodic law in 1871, and published an associated periodic table of chemical elements, authors have experimented with varying types of periodic tables including for teaching, aesthetic or philosophical purposes.Įarlier, in 1869, Mendeleev had mentioned different layouts including short, medium, and even cubic forms.
