Chemistry is an interdisciplinary subject with roots in physics and mathematics. An understanding of the principles of chemistry is essential to the study of many fields of science and technology. The Chemistry Department emphasizes the fundamental principles of chemistry and the development of laboratory skills. We also desire to foster an ethical perspective of the role of science in the world and to develop competent individuals who can provide service to our society.

The chemistry program is approved by the American Chemical Society to certify degrees in chemistry and biochemistry. The ACS certified degree requires additional course work beyond the basic major.

The major prepares students for graduate studies in chemistry, biochemistry, and allied fields; for entry into health professions; for work in industry and government; and for teaching at the secondary level. A sound understanding of analytical and problem-solving skills provides the student with a foundation for engaging in a wide range of service, management, and leadership roles.

Students who complete a Chemistry major are granted a Bachelor of Science degree unless they request a Bachelor of Arts degree.

Basic major requirements comprise 36 hours in chemistry:

*       This includes 32 hours of CHEM 231, 232, 294, 336, 341, 342, 355; either 455 or 457; 371 and 494. (Two hours of CHEM 294 are required, preferably taken each semester sophomore year.)

*       Two elective courses (at least four additional hours) of advanced chemistry are required from the following courses: CHEM 372, 475, 461, 463, 485, and either 455 or 457 (i.e. the one not already taken above), and either 436 or 437. At least one of these elective courses must be a lab course, i.e. CHEM 475, 455, 457, 463, 485.

*       Required supporting courses are 16 hours of: MATH 231, 232 and PHYS 231 and 232.

 

Biochemistry concentration requirements differ from the basic major as follows: CHEM 461, 462 and 463 are required, and the 4 hours of advanced electives are dropped, for a total of 40 hours in chemistry. MATH 231 and either PHYS 221/222 or PHYS 231/232 are 12 hours of required supporting courses.

American Chemical Society certified major requirements beyond the basic major requirements are CHEM 455 or 457 (whichever has not yet been taken), 461, and 485. Also, CHEM 436 must be taken as part of the core requirements rather than CHEM 437. Total = 42 hours.

American Chemical Society certified major with a concentration in biochemistry requirements beyond the basic major (34 hrs) requirements are CHEM 461, 462, and two hours chosen from either CHEM 495 Biochemistry research), or CHEM 485. Total = 42 hours.

Secondary Education with Chemistry Teacher License. Students who desire Illinois state teacher licensure will complete a double major in Chemistry and Secondary Education. However, the Illinois license in this area is much broader than a single subject. This license will entitle the student to teach the beginning level of any science class and advanced levels of Chemistry classes. Students should consult with the Science advisor and the Education Department regarding required classes. A Master of Arts (MAT) program is available with a Chemistry major. A combined Bachelor’s/MAT may be completed in five years and one summer. See the Education Department section in this catalog.

*       Core (28 hours) consists of: CHEM 231, 232, 341, 342, 355, 371, 461, 494.

*       Required supporting courses (28 hours) consist of: MATH 231, 232, PHYS 231, 232; ASTR 301 or 302; SCI 321, BIOL 201, GEOL 211. Total = 56 hours.

 

A departmental honors program for majors requires four hours of honors course work and four hours of research credit (495) including a thesis. Plans should be established no later than the fall semester of the junior year.

Requirements for a minor in Chemistry are 20 hours of chemistry courses, which must include CHEM 231, 232, 241 or 341, and 355. CHEM 203 cannot be used for the minor.

Safety is an integral part of education in chemistry and is emphasized in all laboratories. Students are expected to know and follow safety precautions at all times.
