Element Trek is an interactive Periodic Table of the Elements, augmented with interactive (and animated) 3D models of their crystal structures (see screenshots below) and a vast array of technical data, including 24 plot charts. Using the Bohr model, the electron shells and subshells are presented graphically with the ability to expand any atomic shell into its component subshells to see their electrons. Additionally, there is a scrollable chart that shows the positions of the relative energy levels for all of these shells and subshells from lowest to highest, along with the magic numbers for filled shells.

(The Mac version is now available.)

The absorption spectra and emission spectra of each element can be displayed graphically, and simultaneously in list format that shows the value of each wavelength in nanometers and the wavelength intensity by percentage.

You can view a graphical representation of the melting point and boiling point of each element with simultaneous readouts in Fahrenheit, Celsius, and Kelvins. Additionally there is a chart that plots all of the melting points (and another for boiling points) for all of the elements.

All of the Ionization Energies for each element can be displayed graphically in either eV (electron volts) or switched to kJ/M (kiloJoules / Mole), and dragged across to reveal specific values.

The Periodic Tables shows the atomic number and atomic symbol of each element, and each element entry is color-coded according to the Category of the element. In the main Periodic Table, tapping any element will show the values of various properties of that element in the data readouts section. There are 6 sections of data that can be specified individually, or set to automatically advance and autorepeat.

There is a view which shows a chart of all of the Oxidation States for each each element, listed in ascending order by atomic number.
