Lewis Structures

Bond together atoms to create target molecules with unique bond polarities and molecular shapes.

Topics

Take a peek inside the Lewis Structures game for a brief overview of the concepts covered through gameplay. Learn about the challenge levels, exploratory sandbox, and free teacher resources for use in your chemistry classroom.

Core levels

To successfully create a molecule, students must satisfy the octet (or duet) rule when bonding atoms together. By manipulating the number of shared valence electrons between atoms, students can create single, double, and triple bonds.

Through observing the location of the shared electrons in the bonds created, and the relative electronegativity of the atoms, students will explore non-polar, semi-polar, and very polar covalent bonds.

Students will be introduced to VSEPR Theory by building molecules that match the molecular shapes presented in the targets (linear, bent, trigonal planar, tetrahedral).

Sandbox

The Lewis Structures Sandbox is an open-ended and exploratory environment designed for students to freely build molecules using the provided bank of atoms. Complement your instruction by designing your own Sandbox activities and encourage your students to earn the built-in Achievements that focus on a specific topic within Lewis Structures.

Connected levels

Radii Trends and Lewis Structures

In these connected game levels, there are atoms missing from the provided bank. Students must return to the Radii Trends game to build the missing atoms with the correct number of valence electrons and electronegativity level that they need in order to create the target molecules in the Lewis Structures game.
