From the developer:
Element Trek is an interactive Periodic Table of the Elements, augmented with animated 3D models of their electron orbitals and static 3D models of their crystal structures 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.
