Extractions: "Atomic number" in German is "Atomzahl", so the Z symbol for atomic number probably comes from "Zahl" (number). The Encyclopedia of Symbols has a more poetic interpretation: M is sometimes used for mass number ("Massenzahl" in German), but A is the symbol recommended in the ACS Style Guide [ ]. The symbol may have been chosen so that the positions of the mass and atomic numbers are less likely to be confused in a nuclide symbol: A

Links for Chemists was "born" in June 1995, early versions were merely upgraded or deleted, however an antiquated, unauthorised copy was located on a server in Germany. We have made it available here to demonstrate how far the index has developed in the last few years. In the first few months of the site, the visitors numbered in the low hundreds, by January of 1999, we had broken through the barrier of 10,000 front page visitors per month February 2000 saw 20,000+ unique visitors and by March 2000, this had reached 23,500 unique visitors in one month, or 34,400 including repeat visits.

Extractions: Nuclear Chemistry Discovery of the Particles Growth and Decay Curves The Structure of the Atom Discovery of Particles The discovery of x-rays by William Conrad Roentgen in November of 1895 excited the imagination of a generation of scientists who rushed to study this phenomenon. Within a few months, Henri Becquerel found that both uranium metal and salts of this element gave off a different form of radiation, which could also pass through solids. By 1898, Marie Curie found that compounds of thorium were also "radioactive." After pain-staking effort she eventually isolated two more radioactive elements polonium and radium from ores that contained uranium. In 1899 Ernest Rutherford found that there were at least two different forms of radioactivity when he studied the absorption of radioactivity by thin sheets of metal foil. One, which he called alpha ( ) particles , were absorbed by metal foil that was a few hundredths of a centimeter thick. The other, beta (ß) particles , could pass through 100 times as much metal foil before they became absorbed. Shortly thereafter, a third form of radiation, gamma ( ) rays , was discovered that could penetrate as much as several centimeters of lead.

(in Engl. often spelled Huckel or Hueckel) was born in 1896 in Berlin and died in Marburg Debye a theory of strong electrolytes which became known as the Debye-Huckel theory. He then worked for a while on capillary effects and wrote a book about it. Later on he introduced a theory of the C=C bond based on quantum mechanics which was to become the famous Huckel theory. He left this field of interest after a short while and published thereafter only occasionally on various other topics of physics. by U. Anders, 1992 "... von den Zweifeln zahlreicher Fachgenossen begleitet ..."

Extractions: After having finished my studies at the E.N.S. (Ecole Normale Supérieure) and at the Faculté des Sciences de Paris, I contacted in October 1952 the small Theoretical Chemistry group formed by Mr. and Mrs. Pullman and G. Berthier in order to prepare a thesis. In that period the non-benzenoid aromatic hydrocarbons were under study in that laboratory. As for most parts of work being performed in Theoretical Chemistry, the method in use was the one of Hückel . The introduction, on the one part, of the configuration interaction (CI) and, on the other, of the SCF Roothaan method incited the Pullmans to leave the simple Hückel area in order to see what these new techniques could bring to our research work. Berthier was charged to study fulvene, reduced to its 6 pi-electrons, by the SCF. method while I myself was directed to apply CI on the same molecule, starting from the Hückel functions, the only ones which were available at that time.
