Many other periodic tables use the word interactive to describe themselves while offering nothing more than links to pages of data about elements. Pages of data are fine, and Ptable "outsources" these write-ups to others like Wikipedia and WebElements through the dropdown in the first tab. Ptable shines when used as a true application, more interactive and dynamic than any standalone software. Please continue reading to learn about all the interesting things you can do with Ptable that make Mendeleev's creation come alive.

Working with you to enhance the student experience
MATTER was set up as a non-profit consortium of UK materials science departments in 1993 to develop and help integrate computer-based learning (CBL) materials into mainstream teaching.
Led by the University of Liverpool, MATTER was originally one of over 70 different projects funded by the Teaching and Learning Technology Programme (TLTP).  This phase of the project resulted in the publication in 1996 of the award-winning Materials Science on CD-ROM, with a second version being released in 1998.  This has now become the leading software resource of its type, and is in use in universities throughout the world. In 1997, Materials Science on CD-ROM was unanimously voted by public jury as winner of the Educational Video/ CD-ROM/CDi competition at EUROMAT '97, held in Maastricht, Netherlands.
More recently, our activities have expanded to include the development of science-based software resources for schools, industry and other science disciplines in universities.  In keeping with the explosive growth of the internet in the past few years, all our software is now developed for web-delivery.  For example, in 1999, we worked in partnership with Corus (formerly British Steel) and the University of Birmingham to produce SteelMATTER - a set of on-line resources for ferrous metallurgy.

The interactive Ellingham diagram:University of Cambridge
The interactive Ellingham diagram included within this TLP is a teaching and learning tool, which you can use to obtain a variety of useful thermodynamic information pertaining to a wide range of reactions.

Reading pO2 from the Ellingham diagram:
In to avoid calculating the equilibrium partial pressure for each value of ΔG°, Richardson2 added a nomographic scale to the Ellingham diagram. The equilibrium partial pressure is found as follows:
A line is drawn from the origin of the graph (T = 0, ΔG = 0) through the point on the Ellingham line of interest, at the required temperature. The equilibrium partial pressure is read off at the point where the drawn line crosses the nomographic scale.
