Chemistry

  • A visual intrepretation of the elements

    There exists a natural affinity between iconography and chemistry. Chemistry, in contrast to physics which leans towards abstract mathematical representation and biology with natural form, relies on symbolism which has a very concrete expression through the physical reality of the elements themselves. It is very much a science of the senses but its sights and smells are at a remove from nature and are penned into a symbolic universe much as the alchemists remained sealed in their laboratories in search of the Philosophers' Stone. Thus the chemist, like the alchemist before him, hopes that by reducing nature to its simplest elements and then putting them back together to gain mastery over it. With this end in view, chemistry has evolved as a science based on the symbolism of the chemical elements which are individually loaded with attributes which can inspire artistic expression. These attributes take many forms, historical, geographical, sociological, economic, physical properties and appearance. These attributes ramify when an element’s hermetic isolation is breached and it combines with other elements to produce materials with new properties. There are 110 elements, their standard arrangement is in octaves where the properties of each note are to some extent repeated by heavier elements within subsequent octaves. Because nature is awkward and does not like perfect analogies, after the first two octaves subsequent octaves are disrupted by the introduction additional blocks of elements between the second and third notes for the next three octaves. The sixth octave remains to be completed and awaits the discovery of new elements.

  • Chemical Education Digital Library

    Benzene rings and other aspects of chemistry come alive with these "living textbooks." This collection of key chemistry documents and primers is made possible via the Chemical Education Digital Library (ChemEd DL) and its contains eight separate items. They are called "living" because they are updated by their owners and those responsible for their continued success.

    Users will find "Practice in Thinking: A Laboratory Course in Introductory Chemistry," "Chemistry Leaflets," and "Wiki: Quantum States of Atoms and Molecules" here for their consideration. The Chemistry Leaflets provide an interesting wrinkle as they were originally published between 1927 and the mid-1940s. Visitors shouldn't miss "Chemical Principles through Integrated Multiple Exemplars (ChemPRIME)" as it is designed so that general chemistry concepts can be presented in an order that reflects the conceptual structure of the discipline.

  • Los Alamos National Laboratory's Chemistry Division Presents:Periodic table of the elements

    Originally this resource, the Periodic Table, was created by Robert Husted at Los Alamos National Laboratory during his time as a Graduate Research Assistant.  

    The Periodic Table that you are currently viewing was inherited by the Chemistry Division from the Computer Division who provided the laboratory some of the internets first web sites.

    This page was given a face lift, tummy tuck, and lobotomy in 2002/2003 by Mollie Boorman. All of the graphics (other than the one of the nuclear submarine) were created in Adobe Photoshop and/or Adobe Illustrator in the eye-numbing hours of Mollie's workday. Still to come: grammar changes and newer information. Email Mollie at mboorman@lanl.gov--not just to contribute useful comments and corrections, but because Mollie likes email.

    This page is being offered as a public service to all those wanting to become more educated in the field of Chemistry.  This is an imperfect resource with ambiguities and errors.  If you notice something incorrect about our web page we would be grateful for any pointers.  We welcome any suggestions or comment at nicky@lanl.gov.

    Good Luck, and Good Chemistry.

  • Periodic table with add'l links

    My name is Yinon Bentor, and I created Chemical Elements.com as my 8th grade science project several years ago. Since then, I have continued to update the site in my free time, and the site is now very different from the original design. Since I "completed" the site for my science fair project in early 1996, I have added more information to each of the element pages, changed the layout of the site to make it easier to use, added different ways to view the table, and made the site more aesthetically pleasing. Formerly "The Periodic Table of the Elements on the Internet", the site has moved through several servers (it is currently hosted through Pair Networks) and is now called "Chemical Elements.com".
