Lewis Dot Structures

Service Description

Lewis structures can be valuable tools for chemists in predicting the behavior of molecules. Important pieces of information that can be derived from these models include the molecular shape (using the VSEPR method) and the existence and degree of molecular polarity. This lesson will address the following topics: Lewis dot diagrams, guidelines for drawing Lewis structures of covalent compounds, determining the presence of resonance structures, and using the formal charge method to evaluate competing structures.
