A college-preparatory chemistry education, employing the “atoms first” approach to chemistry, provides foundational information about atoms and molecules that allows for a logical and sequential presentation of topics. Topics of study include classification of matter, atomic structure, spectroscopy, chemical bonding, molecular geometry, physical change, chemical change, stoichiometry, solutions, ideal gases, acid/base chemistry, reduction/oxidation reactions, thermochemistry, thermodynamics, kinetics, and chemical equilibrium. Students are taught to think as chemists to analyze changes in matter using the concepts of chemistry and their mathematical applications.
