About
The Lewis Structure Builder is a web application designed to help guide learners in discovering the rules of assembling Lewis Structures for molecules.

Help
This app is designed to help illustrate the basics of building Lewis Structures. Visit the menu at any time to change which molecule you're working on, or to get help.
Drag the game board around to find all of the atoms or zoom in/out to get a different view.
Drag atoms into positions next to other atoms where they can be bonded to each other. Remember that some atoms can form multiple bonds with others, and some can form double- or triple-bonds!
Toggle between positioning and bonding atoms.
Drag lines between adjacent atoms to create bonds. Tap bonds to break them. Some atoms can form multiple bonds with their neighbors. If atoms are too far apart or need to be repositioned, try toggling back to positioning atoms.
When ready, check your work to complete the molecule or get feedback. Some molecules have atoms with lone pairs have an extra step that will require you to identify them!
