A chemistry and mathematics teaching practice
Review Sessions
LEWIS DOT
NAMING
ALGEBRA
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.
Chemists communicate not only with words, but also with chemical formulas and equations. For such communication to be effective there must exist a format that is standard the world over. Gaining a measure of mastery over this format is the goal of this lesson. The lesson will address two intimately related yet standalone skills: writing chemical formulas given their accepted names, and naming compounds when presented with chemical formulas. The lesson is designed for all levels of high school Chemistry and College General Chemistry. The main emphasis will be on inorganic nomenclature; basic organic skills will be addressed as well. Advanced organic naming will not be covered.
Algebra is used to solve many different types of problems in general chemistry. In this lesson, the fundamental properties of equality will be reviewed with the remainder of the session left for problem solving
