The Periodic Table is a Dashboard widget where you can click on the elements to display basic information: Symbol, Name, Atomic Number, Mass, and the elemental phase under standard conditions. Double-clicking on an element will open a link to that element's webelements.com page for additional information.

What's New

Version 1.5:
  • I've added the ability to select different elemental properties, and the table will remap the colors around these property values. This allows people to observe some basic periodic trends.
  • The user preferences are also stored now, so the widget will always restart with the user's preferred style.

While the Download Now link is correct for the current 1.5 version, the title, description, and developer's web site link are still wrong.
