The Periodic Table of Chemical Elements is considered as the fundamental tool for studying systematically the chemical elements and their compounds. The Periodic Table, as we know it today, has been filled in for many years, mainly from the 18th century, thanks to the contribution of the research work of many chemists and scientists. The structure of the current Periodic Table has evolved considerably since the early work of Alexandre Chancourtois (1862) and William Odling (1864), precursors of well-known chemists Julius Lothar Meyer (1870) and Dmitri Ivanovich Mendeleyev (1871).
It can be said that the Periodic Table is a daughter of the nineteenth century and that arises as a result of the discovery and experimental determination of the "atomic weights" of the chemical elements. It is the first great revolution of modern Chemistry. In the 20th century and with the discovery of "atomic numbers" because of the work of the physicists E. Rutherford (1910) and H.G.J. Moseley (1013) opens a second revolution that provides a stronger scientific basis in the preceding Periodic Tables. Finally, Quantum Mechanics, in the 20s of the last century, gives the theoretical basis of the structure of the Periodic Table that we know and use today.
