A highly Interactive Periodic Table. This is probably the reason you came to this page.

This flash applet representation of the perodic table has many nice features:

• The elements of the table can be colorized to demonstrate attributes of the elements such as melting/boiling point, volume, ionization, density, etc.
• The lanthanides/actinides can be embedded or separate.
• Electrons can be modeled using a Bohr's model or an Energy Diagram.
• It graphs the chosen attribute of the elements versus atomic number.
• It has the ability to rotate the table's columns to place the hydrogen column in other positions.
• Several other features.

Only for die-hards table lovers. Put the elements in their proper locations.

Tennessee table cohort, Michael Dayah produces a similar application demonstrating his prowess in CSS. Knovel has licensed a version of my table for their site.
