Wide version of the periodic table of the elements
See also: Table
This wide version of the periodic Tableau of the elements represents all the chemical elements, grouped by their atomic Orbitale and them electronic Couche.
History
This wide version of the periodic table of the elements was developed by Glenn T. Seaborg in 1969. It is a logical extension of the principles enacted by Mendeleïev in its periodic classification of the elements thus making it possible to include the chemical elements still nonto date discovered. The whole of the chemical elements still nondiscovered is named according to defined by the nomenclature of the UICPA (International union of chemistry pure and applied). This nomenclature makes it possible to create the denomination of an element before its discovery, its confirmation and obtaining its official name.
The symbol in bleu located in top of each column indicates the atomic last Orbitale. The figure in rouge located at the left of each line indicates the period of the electronic last Couche (Note that there are some exceptions, such as the Cuivre).
The Hélium is placed beside the Hydrogène rather than beside the Néon since this one belonged to the group S ².
