OK - started reorganisation of one WebElements area, the "chemistry nexus". The nexus will now bring together news, articles, the WebElements blog, and eventually the Webelements bibliography, and more. It will also contain chemistry content related to WebElements, for instance, sections on the chemistry of the various groups or periods in the periodic table, articles on periodicity, expanded disucssion of the chemistry of specific elements, and so on. All that will take years to add of course. The existing forums site will be located in a dedicated area at the WebElements forum elsewhere.
I'm pleased to announce that you can now buy a Chinese periodic table poster (traditional) at the WebElements shop.
This picture is a wordle. This shows the chemical elements in proportion to pages viewed for each on the WebElements periodic table web site. Hydrogen is the most viewed element. The question is, I suppose, is whether any useful information is conveyed? You can see this wordle and others at wordle.net
I have restructured WebElements. The restructuring is all style at the front-end and reorganisation at the back-end, meaning all the errors in data are still there but they are displayed more beautifully and efficiently. Fixing some of those errors is now a priority.
All this should allow me to update content far more easily than has been the case, meaning things should move quicker. The database is now far simpler and hopefully the addresses like http://www.webelements.com/hydrogen/ far more helpful. I would say the new site is now "beta" meaning it is largely functional but expect glitches for a little while. I have not updated the "scholar" version but will do so if there seems to be a demand. Following this restructuring there are a number of features I am now in a position to implement and this will happen over the next few weeks/months.
Quite significant numbers of you are using the site via iPhones so I am tempted to produce a version for that sort of screen size
Please do let me know by adding comments here if there are features you would like to see.
Quite by chance I noticed that at Simon Fraser University in Canada members of staff in the Department got together to make a periodic table quilt. Looks to be about 6 feet across. I wonder if it will be updated for the latest elements?
If you go to the SFU site, click on any element to see that panel in more detail. Anyone else made a quilt like this?
...as I see the WebElements A6 size periodic table card (laminated, naturally) is the logo for the FaceBook Group "The united nerd front" - A place for nerds to unite. (if you have a mini-periodic table you get gold card membership).
The printable periodic tables held on this site at http://www.webelements.com/nexus/Printable_Periodic_Table have been updated 21 September 2007 to reflect the latest (2007) IUPAC values that will appear shortly in Pure & Appl. Chem. They are pdf files so pretty well anyone should be able to print them.
This stamp commemorates the death of Mendeleev (February 1907), one of the lead figures responsible for the periodic table. Absolutely excellent choice of colours if I might say so! The stamp was sent to me by Prof Gabriel Pinto (Departamento de Ingeniería Química Industrial, ETSI Industriales, UPM, Madrid, Spain) and I quote from his web page:
"This stamp was launched on february 2, 2007, by Correos (Spanish Post Office). It is devoted to Chemistry with the periodic table of elements of Mendeleyéiev. It refers to the periodic classification of the chemistry elements proposed by Dmitri Ivanovich Mendeleyéiev in 1869. As he attempted to classify the elements according to their chemical properties, he noticed patterns that led him to postulate his Periodic Table which described elements according to both weight and valence and which, if arranged according to their atomic mass, exhibited an apparent periodicity of properties. Unlike other contributors to the table he predicted the properties of elements yet to be discovered and made an accurate prediction of the qualities of germanium, gallium, and scandium which came to fill in the empty boxes of his table. Mendeleyéiev (1834-1907) made other important contributions to chemistry such as studies on the expansion of liquids with heat, the invention of pyrocollodion, a kind of smokeless powder based on nitrocellulose and made important contributions to the determination of the nature of such indefinite compounds as solutions. He was the author of Principles of Chemistry, a classic on the subject and for a couple of years was responsible for the Department of Weights and Measures of Saint Petersburg."
