In 1869, Dmitry Mendeleev introduced his colleaguesfrom the Russian Chemical Society a completely new version of the periodic table of elements. 150 years have passed since that moment. But Dmitry Ivanovich is not the only one who managed to organize the elements in such a way that they showed the complexity of the structure of the universe and matter. A large number of researchers from around the world have tried their hand at classifying and organizing 63 elements known at that time. Recall that to date, at least 118 elements have been discovered, including attempts to rearrange them in the strangest and most unusual tables. From this article you will find out how unusual a familiar and familiar table may appear to us all.
Recall that the table of chemical elements of Dmitry Ivanovich Mendeleev is presented in the form of a periodic law. Its modern wording is: the properties of elements are periodically dependent on the charge of their atomic nuclei. At the time of writing, over 500 have been published.variants of the periodic system for the classification of chemical elements, which is associated with attempts to find a solution to some particular problems of its structure. By decision of the UN, 2019 was proclaimed the International Year of the Periodic Table of Chemical Elements.

Periodic table D.I. Mendeleev
Regardless of whether you love or hateher, before you is the original periodic table and, most likely, you will always recognize her. This system of classification of chemical elements is familiar to us from childhood and is ordered by atomic number, electronic configuration. It should be noted that it weakly depends on the chemical properties of the elements as such. There are fewer elements in this version of the table, but there is room for more unexposed elements, which - as the years of research have shown - turned out to be a reasonable assumption by a Russian scientist.
"Tower" of chemical elements
ADOMAH Periodic Table developed in 2006year Valery Zimmerman. Instead of being based on atomic numbers, systematized around four quantum numbers of electronic configuration, these four numbers are used to describe the location and movement of electrons inside an atom. The idea originates from an older table.engineer and biologist Charles Janet, according to an article published on the Science Alert portal. His work rebuilt the elements in accordance with orbital filling - the main probability of finding an electron at a certain distance from the nucleus of an atom.

Chemical element spiral
Spiral table of chemical elements,created in 1964 by the chemist Theodore Benfei, looks very beautiful. Starting from the middle of the hydrogen helix, it is twisted outward in the order of atomic numbers before it branches into transition metals, lanthanides, actinides and still not discovered superactinides.
It is noteworthy that in this periodic tablethere is neither hydrogen nor helium. The first turquoise colored section (or petal) contains alkali metals in front and alkaline earth metals in the back. Other petals, in turn, contain other elements grouped by their inherent qualities.
Tape of Periodic Chemical Elements
Below you can see the moving variation: Called the periodic table by a twisted ribbon, the table was created by James Franklin Hyde in 1975. Hyde was a chemist studying silicon organics, and therefore placed silicon at the center of the table (in the beige section in the middle of two circles), emphasizing the strong connection of this element with many others in the table.
In the periodic system of chemical elements for each element, its symbol, name, serial number and relative atomic mass are indicated.
However, the table still starts in the center.right circle with hydrogen before spiraling out into different groups. Many colors emphasize the periodic relationships of the elements. Beautiful bends make this one of our favorite options, but it is also quite intense. For a practical look at things, check out this periodic table that tells you how to use these elements.
