Periodic Tables and Related Material

• WebElements
  By Mark Winter, University of Sheffield in South Yorkshire, England. WebElements is a WWW periodic table database and utility packages constructed with data abstracted from the HyperCard program MacElements. Other features of WebElements are an isotope pattern calculator and an element percentage calculator. Due to the early presence and popularity of WebElements, there is a number of local mirrors/implementations of older versions of WebElements to be found at:
  
  • University College (UNSW) Australian Defence Force Academy [Australia]
  • Technical University of Wienna [Austria]
  • State University of Campinas [Brasil]
  • Institute of Chemical Metallurgy - Chinese Academy of Science [China]
  • University of Erlangen [Germany]
  • University of Regensburg [Germany]
  • Boston College [USA]
  • Boston University [USA]
  • University of California at Berkeley [USA]
  • University of Chicago [USA]
• Chemicool Periodic Table
  This graphics periodic table implementation provides for each element general information, states, energies, oxidation & electrons, appearance & characteristics, reactions, other forms, radius, conductivity and abundance, as well as links to Encyclopedia Britannica articles. There's also a less graphics version in case you're on a slow link. In addition to pure periodic data, this site also offers graphs of atomic weight, atomic radius, and ionization energy vs. atomic number.
• HP 48GX Periodic Table of the Elements Library
  The HP 48 Periodic Table Library is a RAM-based version of the Periodic Table application that was originally distributed in the HP 82211A HP Solve Equation Library Card. Freeware.
• HyperProg Periodic Table Bundle
  Demo versions of Mac Hypercard decks containing two parts, one that helps you learn the Periodic Table of Elements (elements 1-111) and one that tests you on how well you know them.
• Illinois Institute of Technology
  A click on an element name button in the forms-based periodic table at this site will give you the X-ray properties of that element. If you give an energy value in a box at the top of the table then you also get x-ray cross-sections at that energy. The source code used to calculate x-ray cross-sections is also available.
• Illinois State Geological Survey
  This link brings you to both a table-based and a text-only periodic table implementation.
• Isotopic Abundances of the Elements
  This link to "Mass Spec Tools" includes a periodic chart with graphic hyperlinks to charts with exact masses and isotopic abundances of the elements and mass spec calibration data (plus lots of MS-specific information).
• Los Alamos National Laboratories
  This is a periodic table based on a clickable bitmap. Although limited with respect to hard, tabular, numerical facts, it contains nicely written articles on each element, providing more background information (discovery, uses, etc) than other web tables.
• NMR Periodic Table
  A different kin dof periodic table, that provides data on spin, natural abunance, magnetogyric ratio, relative receptivity, magnetic moment, quadrupole moment, and pesonance frequency for each element.
• Particle Physics Booklet - Table of Contents to Images
  A perfect complement to the periodic tables - A booklet of particles that build the elements! This Booklet is extracted from the Review of Particle Properties, Physical Review D50, 1173 (1994). The full Review lists all the data, with references, used in obtaining the values given in the Particle Summary Tables. It also contains much additional information. Some of the material that does appear in this Booklet is only an abbreviated version of what appears in the full Review.
• Periodic Table of the Elements
  A minimalist text-based periodic table implementation from the University of Kansas.
• Periodic Table of Elements Information
  This link does not point at a periodic table. Instead it contains brief information on what information you can derive from a periodic table and also how the general property trends of the elements vary in the periodic table.
• Periodic Table of the Elements
  Tables-based implementation by the semi-anonymous creator asia@universe.digex.net. "The only Periodic Table on the net with a sense of humor and reference to Greek Mythology."
• Periodic Table of the Presidents
  A distinctly different kind of periodic information.
• PM Periodic Table
  A periodic table for the OS/2 desktop! Now, the chemical information you also need is only a mouse click away! (Well, at least some info is....) The program includes the names, symbols, atomic number and atomic masses of the elements in a standard periodic table format. PM Periodic Table is registerware, which means that it is FREE!
• Periodic TablETRIS
  A program designed to enhance your memory of the element positions in the Periodic Table. Play like Tetris. Place the elements in their correct positions as fast as you can to get the higher score. Shockwave version (play on-line), and downloadable programs for Mac and Windows available.
• Table of Isotopes
  The data in the Table of Isotopes from the Lawrence Berkeley National Laboratory are based on the Evaluated Nuclear Structure Data File ENSDF maintained by the National Nuclear Data Center at Brookhaven National Laboratory. Information on a number of topics relating to nuclear science are available on-line from this site, including Nuclear Structure and Decay Data, High-Spin Nuclear Data, Nuclear Astrophysics Data, Atomic Mass Data, Nuclear Moments, Fundamental Constants, Periodic Table, Chemical Properties, Elemental Abundance, and Isotopic Abundance. Some of these documents are available only in PDF or PostScript format.
• The Periodic Table of Elements on the Internet
  "The Most Complete Internet Periodic Table created in the United States." The seemedly pretentious title and quoted epithet are fully adequate, when taking into account that the table in question was created by Yinon Bentor as an 8th grade science project!!! Let's hope we get more submissions like this!
• The Smallest Periodic Table on the Web
  You should have dozens of it on your screen already, and it simply can't be smaller! The bullet used on this site to mark a link leading to a periodic table is in fact a true one pixel/element periodic table itself, indicating the acid-base properties of the elements. Various shades of blue and red indicate basicity and acidity, and green denotes amphoteric properties. Grey marks absence of, or unknown, acid-base character. Useful as a table? Questionable, but as an annotation bullet: Yes!
• University of British Columbia
  This table-based periodic table provides basic numerical data on each element. You can also have the elements listed by atomic number, name or symbol. The old text-based implementation is still alive.
• University of California at Santa Barbara
  A Gopher-based periodic table.
• University of Texas Southwestern Medical Center
  Yet another clickable graphic Periodic Table of the Elements.
• WINPTE - Periodic Table for Windows
  WINPTE is an easy-to-use version of the Periodic Table. It provides you all basic information about the elements, and makes it easy to share the data with other programs. One important feature is that you, the user, can translate the program without recompiling. This way WINPTE can be used in education all over the world. When indexed, localized Finnish, German and French versions were available. Shareware - Registration fee: US$ 20.
