Lewis Structures, VSEPR and Molecular Modeling

Learners practice drawing Lewis dot structures, build molecules with model kits, and predict molecular shapes using VSEPR theory. The combination of written work and hands-on reinforcement benefits young scientists.

In this drawing Lewis structures worksheet, students read about the 5 steps taken to draw Lewis structures for atoms and molecules. These include identifying the valence electrons, placing pairs of electrons between atoms to be bonded,...

Atomic models help us visualize the interactions of substances we cannot see. Explore atomic models, specifically Lewis structures, that show valence electrons and their role in bonds.
