Chemical Valence is an app designed to help you learn the basics about chemical bonding. This app provides a fun game-like, intuitive interface in which you push valence electrons around to make molecules. If you form the correct 2D Lewis dot structure, you are rewarded with a rotatable 3D structure that helps you visualize the real geometry of the molecule. As your understanding grows, each level gives you more complicated structures to solve. Use the narrative, definitions and open-ended reflection questions (with hints!) to guide your understanding. This app is suitable for individual study or for use in a classroom.

A powerful tool for teaching
I'm not a chemist, but the interactivity here made me feel as though I finally understood molecular bonds!
