Janet is known almost exclusively for his left-step periodic table (LSPT). A study of his writings shows him to have been a highly creative thinker and a brilliant draftsman. His approach was primarily arithmetic-geometric, but it led him to anticipate the discovery of deuterium, helium-3, transuranian elements, antimatter and energy from nuclear fusion. He recognized the (n + ℓ) rule well before Madelung and correctly placed the actinides. His controversial treatment of helium at the head of… 
Viatscheslaw Romanoff: unknown genius of the periodic system
Abstract The history of chemistry has not once seen representations of the periodic system that have not received proper attention or recognition. The present paper is dedicated to a nearly unknown

The first attempt to represent the Periodic system graphically was the Telluric Helix ( Vis Tellurique ) presented in 1862 by Alexandre-Emile Béguyer de Chancourtois, in which the sequence of

Biographies have been written of people, chemicals, and devices like zippers. Here is the biography of a periodic table. The spiral table in the student magazine Chemistry was introduced in 1964 to
Matter-Antimatter : An Accentuation-Attrition Model
A system of matter dissipating antimatter and parallel system of antimatter that contribute to the dissipation of the velocity of production of matter is investigated. It is shown that the time

The notion of an ‘optimal’ periodic table is discussed in the context of recent work by philosophers of science who have examined the nature of classifications in general, as well as the notion of natural kinds.
Binódic periodic system: a mathematical approach
This article discusses the mathematizing of the chemical periodic system as a grid, which leads to a quadratic function or “binódica function” formed by pairs of periods or binodos (dyads). We
Tetrahedral and spherical representations of the periodic system
The s, p, d and f blocks of the elements, as delimited by Charles Janet in 1928, can be represented as parallel slices of a regular tetrahedron. They also fit neatly on to the surface of a sphere.


A century on from Dmitrii Mendeleev: tables and spirals, noble gases and Nobel prizes
Mendeleev’s failure to represent the periodic system as a continuum may have hidden from him the space for the noble gases. A spiral format might have revealed the significance of the wide gaps in
The Periodic Table: An Eight Period Table For The 21st Centrury
Throughout most of the 20th century, an eight-period periodic table (also known as an electron-configuration table) was offered as an improvement over the ubiquitous seven-period format of wall
The Role of Triads in the Evolution of the Periodic Table : Past and Present
The purpose of this article is to propose a new design for the presentation of the periodic system of the elements. It is a system that highlights the fundamental importance of elements as basic
The Periodic Table: Its Story and Its Significance
The periodic table of elements is among the most recognizable image in science. It lies at the core of chemistry and embodies the most fundamental principles of science. In this new edition, Eric
