Interactive Periodic Table

This is a really cool website: Interactive Periodic Table of the Elements.

Use the hyperlinks in the left column to manipulate the Table. You can change it to show the full names of elements instead of their symbols, to show their date of discovery, melting point, etc. You have it display only halogens, rare earth elements, noble gases, etc.

The best part, I think, is that you can click on any element within the Table and learn ALL about it.

Great little learning tool.
