A modification of the regular medium-form periodic table is presented in which certain elements are placed in more than one position. H is included at the top of both the alkali metals and the halogens; He is above Be and above Ne. The column of noble gases is duplicated as Groups O and 18. The elements of the second and third periods are duplicated above the transition metals. This arrangement displays more patterns and connections between the elements than are seen in the regular format. It… 

On the ‘true position’ of hydrogen in the Periodic Table

Several attempts have recently been made to point to ‘the proper place’ for hydrogen (sometimes also helium) in the Periodic Table of the elements. There are altogether five different types of

Explaining the periodic table, and the role of chemical triads

Some recent work in mathematical chemistry is discussed. It is claimed that quantum mechanics does not provide a conclusive means of classifying certain elements like hydrogen and helium into their

A Comparative Study of the Physical and Mechanical Properties of Hydrogen Using Data Mining Research Techniques

Hydrogen was the first element to exist in the universe. It is the lightest and simplest element, but chemists do not agree about its placement in the periodic table; its position has given rise to



The Proper Place for Hydrogen in the Periodic Table

This paper addresses the problem posed by the location of hydrogen in the currently used periodic table and offers evidence supporting the assertion that hydrogen should appear directly above carbo...

A Revised Periodic Table: With the Lanthanides Repositioned

The lanthanide elements from lanthanum to lutetium inclusive are incorporated into the body of the periodic table. They are subdivided into three sub-groups according to their important oxidation
