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.

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.

Requirements

Mac OS X 10.4 or later
