CEM 151 – General and Descriptive Chemistry
Description:
In this non-mathematical course, we emphasize conceptual and descriptive chemistry.
We first review atomic structure and examine in detail some of the properties of the
outermost electrons on the atom, the valence electrons, because these determine the
chemical properties of the atom. These electrons may be either transferred to other
atoms that attract the electrons more strongly (forming ionic bonds), or may be shared
with electrons on other atoms (forming covalent bonds). We note that shared
electrons may have directional characteristics that we strive both to explain and
predict. We first examine the behavior of representative s- and p-block (main group)
elements. We then examine the rich (complicated) coordination chemistry of the dblock (transition) metals and end the course with discussions on “modern materials.”
