Inorganic chemistry is one of the major fields of chemistry along side organic, physical, and analytical chemistry. In inorganic chemistry we examine the chemistries (and properties) of all the elements of the periodic table and find applications in many fields ranging from material development to medicinal applications. This course will offer in introduction to some of the key concepts needed to fully develop an understanding of inorganic chemistry and to develop a greater understanding of chemistry in general. We will see examples of how inorganic chemistry plays an important role in everyday life and will try to examine some applications of inorganic chemistry. The main goal of this course is to offer an introduction to several key concepts that can be applied in inorganic chemistry and in other fields of chemistry. A more developed investigation of inorganic chemistry (compounds, reactivities and applications) is seen in Inorganic Chemistry II (CHM225) for which this course is a pre-requisite.
