Alternative periodic tables

Alternative periodic tables differ in presentation and classification of the chemical elements from the traditional periodic table. Since was a systematic relationship between atomic mass and chemical properties of the elements discovered, there were several alternative proposals to the Dimitri Ivanovich Mendeleev from (1834-1907) and Lothar Meyer (1830-1895) established order of the elements. However, this periodic table is the generally accepted periodic table in chemistry.

Janet Periodic Table

Charles Janet created a periodic table, in which the elements were arranged according to blocks. In a block the chemical elements according to the highest-energy orbitals of their electron shells are summarized. This periodic table is still in use today sometimes in physics.

Elements Spiral

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

Flower periodic table

The flower - period system is spatial. The elements are shown in ascending order of atomic number as a wound tape. The transition group elements and the actinides and lanthanides each form a loop in addition to the main group elements.

The Periodic Table of Stowe

Also, this period is three-dimensional system. The periodic table has three axes which represent the principal quantum number, the quantum number, and the magnetic quantum number. The periodic table is named after its inventor Timothy Stowe.

The Periodic Table by Better Man

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