Mark Winter's WebElements, ver. 2.0

An excellent periodic table if you want data (LOTS of data) on an element.

Periodic Table Live!

This spectacular effort is hosted by the Journal of Chemical Education. It contains all kinds of data on the elements, still pictures of samples, and the elusive videos (QuickTime) of many elements reacting with air, water, acid and base.

Shockwave Periodic Table

This table from the American Chemical Society employs Shockwave and includes the typical data as well as electron configurations and the ability to plot various properties versus atomic number.

Chemicool Periodic Table

Designed and maintained by David Hsu, this one has good basic data, some reaction information, etc. A nice-looking graphic interface.

The CRC Periodic Table

That section at the front of the CRC that has all the stuff about the elements? It's now available (free) on-line.

Printable Periodic Table (Excel Template)

Created by Dr. John Witter of Vertex42, this is a periodic table you can customize and print, driven by an Excel spreadsheet chock full of data. The potential result is reminiscent of those wonderful old two-sided Sargent-Welch periodic tables but with more flexibility and the ability to keep up-to-date with newly christened elements. No macros, just a straightforward spreadsheet. Two print-ready tables are available at the site along with the Excel template for customizing your own. Free!!

ChemGlobe's Periodic Table of the Elements

Historical information, isotopes, physical and atomic properties and more. From Paul Kremer.

Touchspin Periodic Table

This is actually a customization of the Flash table by Touchspin. A lot of very tiny data and some fancy graphical information in this table. Takes some getting used to.

Wikipedia Periodic Table

One could hardly ignore this inevitable and (seemingly) exhaustive version of the periodic table. Clicking on an individual element leads to a tremendous amount of "stuff" about it.

Dynamic Periodic Table

It's that and more. A very slick interface that cobbles together information and data from all over the place.

Dow/PopSci Periodic Table

The folks at Dow Chemical and Popular Science have joined forces to mount a Flash table that uses Theodore Gray's [see Wooden Periodic Table below] beautiful pictorial table as a front-end. There is only minimal data here but if you are looking for images of the elements, each link contains another link back to Grey's site (theodoregray.com) and lots of images of each element--as well as the option to purchase the table poster itself.

Periodic Table from Spectrum Laboratories

Each element symbol links to a page of extensive data and background information on the element. Most of the background information comes from the CRC Handbook.

Periodic Table of the Elements

Excellent table with physical and chemical data as well as some historical background. From Eni Generalic, Split, Croatia.

The Periodic Table, v. 2.5

An excellent offering from Soft Ciências, including biographical information on many scientists, pictures of most elements and a brief history of their discovery, much data, etc. Some construction still going on, but largely complete. Miguel Marques.

Elemental Spectra

This is a very slick JAVA table from the Physics Applets project at the University of Oregon. You select an element and view its absorption or emission spectrum. You can also scan through the spectrum and check the wavelength of each line.

Periodic table of minerals

From Webmineral.com, this table includes extensive lists of mineral compositions for each element, borax and phosphate bead tables, and a table of emission spectra for many elements.

The Visual Elements Periodic Table

Part of a visually stunning site maintained by the Chemical Society, this table incorporates original art work along with general background on each element and some data in PDF form. You will need the Adobe Acrobat reader for the data. Some of the art work is available for download as screen savers and backgrounds.

The Periodic Table of Videos

While we're in the UK we should not ignore this entry from the University of Nottingham. The videos cover a range from demonstrations of various reactions of the elements to discussions of the background or uses of the elements. The videos are.......special :-)

Periodic table applet

This JAVA applet from Visual Entities gives the usual information but in an interesting and slick fashion. Somewhat unique is the sliding scale for data such as discovery date, abundance, melting point, etc. Worth a look.

Printable periodic tables

These files were prepared by Scott Van Bramer at Widener University and are in Adobe Acrobat format which means they make you want to run to the optometrist when you see them on your screen but they print beautifully. All the most current information up to element 118!

And just for fun......

Elements in the Comics: A comic book periodic table

Remember the Metal Men? Well, you have to be of a certain age... Anyway, this is a fun place if you have ever had any connection with comic books. From Jim Holler and Jack Selegue at the University of Kentucky.

The Wooden Periodic Table

Surely one of the more unusual entries in the seemingly endless category of online periodic tables. Definitely more than a weekend project. Some chemistry here, but mostly just whistles of amazement---and pictures of many of the elements.

The Elements, by Tom Lehrer

An MP3 version of the classic recording. From Harry Clark's Chemistry Web site at Jesuit High School.

The Elements, by Tom Lehrer

O.K., O.K....this is the last one! Very cleverly animated in Flash. From Mike Stanfill, a graphic designer at privatehand.com
