Interactive Chemistry
https://interactivechemistry.orgThis game allows you to bond atoms together to create molecules using 21st Century Lewis Dot Models. You can build molecules containing carbon, hydrogen, oxygen, nitrogen, and chlorine atoms. Molecules can range from 2 atoms up to 16 atoms! The interface is intuitive and visually pleasing, and sound effects are used to provide encouragement.
