Chemical Connections and Happening

Transferring electrons. Making and breaking chemical bonds. These are among the atomic- and molecular-scale happenings that we will explore in this course, combining discussions of chemical principles with hands-on laboratory experiments. \ This is an auspicious year for chemistry: 2019 has been designated by the United Nations General Assembly and UNESCO as the International Year of the Periodic Table of Chemical Elements, in honor of the 150th anniversary of Dmitri Mendeleev’s publication of his periodic table. Along these lines, we will investigate some elemental properties through laboratory experiments on oxidation-reduction reactions and acid-base chemistry. We will also use hand-held models and computer software to visualize three-dimensional molecular structures and to calculate the distribution of electrons within molecules. Finally, we will consider connections of chemistry to philosophical, artistic, and literary questions, such as levels of “truth” in scientific theories. Curiosity and interest in chemistry are pre-requisites, but no special chemistry knowledge or background is required.
