The Periodic Table

It is a simple periodic table where you can click on the elements to display basic information: Symbol, Name, Atomic Number, Mass, and Phase under standard conditions.

Double-clicking on an element will open a link to that element's Wikipedia page for additional information. It provides 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.
