Alternative periodic tables

Alternative periodic tables differ from the traditional periodic table in the representation and assignment of the chemical elements . Since a systematic connection between atomic mass and chemical properties of the elements was discovered, there have been several alternative proposals to the order of the elements established by Dimitri Iwanowitsch Mendelejew (1834–1907) and Lothar Meyer (1830–1895). However, this periodic table is the commonly used periodic table in chemistry .

Janet periodic table

Charles Janet created a periodic table in which the elements were arranged in blocks. The chemical elements are grouped in a block according to the energetic orbitals of their electron shell. This periodic table is still sometimes used in physics today.

Elements spiral

Theodor Benfey developed a system in which the chemical elements are arranged in a spiral. Hydrogen is the center of the spiral. The elements with increasing mass are arranged around the center.

Flowers periodic table

The flower periodic table is spatial. The elements are shown as a wound tape in ascending order. The subgroup elements as well as the actinides and the lanthanoids each form a loop next to the main group elements .

The Stowe Periodic Table

This periodic table is also three-dimensional. The periodic table has three axes which are the principal quantum number , the quantum number , and the magnetic quantum number represent. The periodic table is named after its inventor Timothy Stowe.

Bettermann's periodic table

The Bettermann periodic table is derived from the isoelectronic series of the elements. Eugenie Lisitzin showed in 1936 that this series can be represented as a polynomial. The valence electrons of the atoms also show a similar behavior.
