Abstract

An example about the use of everyday phenomena in teaching general chemistry is given. Students have a greater appreciation of the principles of chemistry if they can see the relevance to their lives. Fluorine compounds in dental applications (as topical or as systemic use) provide an excellent context in which to review core content of general chemistry, namely, stoichiometry, concentration units, physiological importance of elements, resonance of polyatomic ions, bond order, bond length, geometry of polyatomic ions, and treatment of water. A set of questions, covering the cited topics, and the corresponding answers are presented to encourage critical thinking from students.
