Periodic tables of elements you've never seen

It has been 150 years since Dmitry Mendeleev presented his version of the periodic system, and all this time there have been no attempts to improve it. If only because Mendeleev himself admitted that the table is incomplete, it leaves room for elements that have yet to be discovered. If so, why not organize its structure differently?


Proposed in 2006 by Vitaly Zimmerman based on the ideas of Charles Janet. He studied the orbital filling of atoms - how the electrons are positioned relative to the nucleus. And on the basis of this, he divided all the elements into four groups, sorting them according to the configurations of the position of the electrons. The table is extremely simple and functional.

Spiral table

In 1964, Theodore Benfey proposed to place hydrogen (H) in the center of the table, and place the other elements around it in a spiral that spins clockwise. Already at the second turn, the helix stretches into loops, which correspond to transition metals and lanthanides with actinides, a place is provided for so far unknown superactinides. This gives the table the look of an extravagant design solution.

3D flower table

There is no separate place for hydrogen, it is, as it were, in the center of the entire structure. One of the petals contains alkali metals, the other contains alkaline earth metals. The rest are distributed among the petals, depending on their elemental qualities. There are versions of the table in the form of a tree with branches.

Rainbow Spiral Table

Invented in 1975 by chemist James Hyde. He was fond of organosilicon compounds, so it was flint that got into the base of the table, since it has a large number of bonds with other elements. Various categories of elements are also grouped into sectors and marked with the desired color. The table is more beautiful than analogs, but because of the curvilinear shape it is not easy to use it.
