Lewis Structures, VSEPR and Molecular Modeling
A model is worth a thousand words. Young scholars use what they know about the structure of hydrocarbons to build Lewis dot structures and molecular models. Their tasks include multiple bonds, geometric hybrids, and various isomers.

Practice Drawing Lewis Structures
Twenty-six elements, compounds, and ions are randomly listed for chemistry whizzes to analyze. They are to diagram the Lewis electron dot structure for each, resulting in further insight on the configuration of different molecules. They...
