[en] Mendeleev’s fame includes: the Periodic Table of Elements, non-election to the Russian Academy of Sciences in 1880, member of 150 academies and societies: For.MEM.R.S., Paris, Bologna, Accademia Dei Lincei, Rome, etc., and broad spectrum of interests and publications (25 volumes).

[en] Many of us grew up being taught that the standard atomic weights we found in the back of our chemistry textbooks or on the Periodic Table of the Chemical Elements hanging on the wall of our chemistry classroom are constants of nature. This was common knowledge for more than a century and a half, but not anymore. The following text explains how advances in chemical instrumentation and isotopic analysis has changed the way we view atomic weights and why they are no longer constants of nature.

[en] Recent experiments to synthesize the heaviest elements have dramatically expanded the periodic table and the Segrè chart of nuclides

[en] Relativistic effects are defined as the difference between the case of a finite speed of light as in the world we live in and of an infinite speed of light as assumed by most theoretical chemistry. Ways in which these relativistic effects can be used to explain some of the most conspicuous anomalies in the latter half of the periodic table comprise this article. These relativistic effects are found to be particularly strong around gold in the table

[en] Some historical facts about the construction of a periodic system of chemical elements are reviewed. The Madelung rule is used to generate an unusual format for the periodic table. Following the work of Byakov, Kulakov, Rumer and Fet, such a format is further refined on the basis of a chain of groups starting with SU(2)xS0(4.2)

[en] Isotopes and nuclides are important in our everyday life. The general public and most students are never exposed to the concepts of stable and radioactive isotopes/nuclides. The National Nuclear Data Center (NNDC) is involved in an international project to develop a Periodic Table of the Isotopes for the educational community to illustrate the importance of isotopes and nuclides in understanding the world around us. This effort should aid teachers in introducing these concepts to students from the high school to the graduate school level
