Use of the periodic table to show variation of physical and chemical properties of the elements. Elements studied as families. Properties such as acid-base, redox, and coordination compounds are related to the position of the element in the periodic table. Prerequisite is the successful completion (grades of C- or better) of CHEM 111 and CHEM 112. It is highly recommended to have successfully completed CHEM 310 and CHEM 451. Spring, even years.
