The ''periodic table'' of the [[chemical]] ''elements'' (also periodic table of the elements or just periodic table) is a tabular display of the chemical elements. Although precursors to this table exist, its [[invention]] is generally credited to Russian chemist [http://en.wikipedia.org/wiki/Dmitri_Mendeleev Dmitri Mendeleev] in 1869, who intended the table to [[illustrate]] recurring ("periodic") [[trends]] in the properties of the elements. The layout of the table has been refined and extended over [[time]], as new elements have been [[discovered]], and new [[theoretical]] [[models]] have been [[developed]] to [[explain]] chemical [[behavior]].

The periodic table is now ubiquitous within the [[academic]] [[discipline]] of [[chemistry]], providing an extremely useful framework to [[classify]], systematize, and [[compare]] all of the many [[different]] [[forms]] of chemical [[behavior]]. The table has found wide [[application]] in [[chemistry]], [[physics]], [[biology]], and engineering, especially chemical engineering. The current standard table contains 118 elements as of March 2010 (elements 1–118).
