The periodic table , also known as the periodic table of elements , is a tabular display of the chemical elements , which are arranged by atomic number , electron configuration , and recurring chemical properties. The structure of the table shows periodic trends. The seven rows of the table, called periods , generally have metals on the left and nonmetals on the right. The columns, called groups , contain elements with similar chemical behaviours. Six groups have accepted names as well as assigned numbers: for example, group 17 elements are the halogens ; and group 18 are the noble gases.

Periodic table

An interval in square brackets provides the lower and upper bounds of the standard atomic weight for that element. For users needing an atomic-weight value for an unspecified sample with disregard to the uncertainty, the conventional values are provided. No values are listed for elements which lack isotopes with a characteristic isotopic abundance in natural terrestrial samples.

Holden, Tyler B. By virtue of its work in relation with the chemical elements, IUPAC can dispense a periodic table that is up-to-date. IUPAC involvement covers various aspects of the table and data that it unveils, and several reports and recommendations, some quite recent, attest of that input. The table is yours to use. Details about the latest release are provided above. Criteria and guidelines for establishing priority of discovery of potential new elements are presented.

While an element can have been claimed, before the claim has been validated and before the element is formally named, the element has a temporary name and symbol. Claims for the discoveries of new elements appear time to time in the scientific literature. In result, IUPAC technical reports are released that review each pertaining references and recognize the laboratory ies whose claims fulfill the agreed criteria. When the discovery of a new element has been validated and the priority for its discovery has been assigned, the naming process can begin.

The Laboratory to which the discovery has been assigned is invited to propose a name and symbol. IUPAC will then review the proposal, and if agreed, after an additional 5-month public review, will formalize the name. For a reflection on the experience of the naming of elements, see Chem Int Apr , pp. Both the root and the ending must be consistent with the agreed recommendations. The detailed recommendations were published in and a revision published in to better accommodate element in group 17 and Actinoids include Ac to Lr.

The question of precisely which elements should be placed in group 3 has been debated from time to time. More recently, on 5 June , CIAAW recommended changes to the standard atomic weights of 14 chemical elements — see release.
