Chemistry is the science that seeks to understand the structure and composition of matter and the changes that it undergoes. The atomic/molecular perspective of chemistry provides fundamental insight into the macroscopic world of materials and organisms. Chemists apply this insight in many ways, such as the synthesis of new substances with useful technological or therapeutic properties and the discovery of new analytical methods that can be used in medicine and environmental science. Coursework in chemistry seeks to acquaint students with fundamental chemical principles, teach students to apply these principles broadly and effectively, and enable students to evaluate critically the impact of chemistry on society.

In addition to providing a working knowledge of chemical principles, a major in chemistry offers experience in critical thinking, data analysis and experimental design. Chemistry graduates pursue a variety of careers in which these skills are important. Many work as chemists in chemical or pharmaceutical companies or in government labs. Others apply their chemical skills to careers in medicine, law, business, chemical or pharmaceutical sales, biotechnology, pharmacology, toxicology or environmental science. Many chemistry graduates pursue careers in education at the secondary, college or university level.

The department emphasizes the importance of research experience. The opportunity to engage in an original research investigation, in collaboration with a faculty member, is a distinctive feature of this program.

The chemistry major may be pursued under either the Bachelor of Arts or the Bachelor of Science degree programs. Students interested in biochemistry should consider either the Bachelor of Science in chemistry curriculum with biochemistry and biology electives or the Bachelor of Science program in cell biology/biochemistry offered jointly by the chemistry and biology departments.

A Bachelor of Arts major consists of eight course credits in chemistry numbered 211 or above, five of which are required: CHEM 211, CHEM 212, CHEM 221 (or CHEM 222, by permission), CHEM 231, and CHEM 340 or CHEM 341. In addition, one semester of calculus (MATH 201) and one semester of physics (PHYS 211) are required. MATH 202 and PHYS 212 are strongly recommended.

A Bachelor of Science major consists of 10 course credits in chemistry numbered 211 or above, eight of which are required: CHEM 211, CHEM 212, CHEM 221 (or CHEM 222, by permission), CHEM 231, CHEM 322, CHEM 332, CHEM 341, and CHEM 342. The sequence of chemistry courses indicated below is strongly recommended; exceptions to this sequence are rare, and each must be negotiated with the student's adviser on the merits of the particular case.

The chemistry major under the Bachelor of Science program also requires three courses in mathematics (MATH 201, 202, and 211), three courses in physics (PHYS 211, 212, and 235), and one science elective.

The recommended sequence for the Bachelor of Science major is as follows:

First Year

First Semester: CHEM 211; MATH 201
Second Semester: CHEM 212; MATH 202

Sophomore Year

First Semester: CHEM 221; MATH 211; PHYS 211
Second Semester: CHEM 231; PHYS 212

Junior Year

First Semester: CHEM 341; science elective
Second Semester: CHEM 322; CHEM 342; PHYS 235

Senior Year

First Semester: CHEM 332; Elective in chemistry
Second Semester: Elective in chemistry

During the junior year ELEC 105 in either semester may be substituted for PHYS 235. The science elective may be selected from the following list of courses and can be taken at any time once the prerequisites for the selected course are satisfied: BIOL 205; CHEG 450; CSCI 202; CSCI 203; GEOL 305; MATH 212; PHYS 317, PHYS 310, PHYS 332, or PHYS 333 or other courses with department approval. Electives in chemistry during the senior year may be chosen from any of the 300-level undergraduate courses in chemistry or CHEM 403. No more than two credits of research, CHEM 375-376 or CHEM 403, may be applied toward the minimum 10-course major.

Advanced placement credit accepted by the University will count as a credit toward graduation, but will not replace the number of chemistry courses above 211 that are required for a major in chemistry.

Transfer students who are given at least 1.5 transfer credits toward graduation based on two semesters of general chemistry taken prior to transfer will be given an adjustment such that those two courses will replace the specific requirement for CHEM 221 and will count as one of the chemistry courses required for the chemistry degree.

Bachelor of Science graduates will not automatically achieve the American Chemical Society's certification. To fulfill these requirements, Bachelor of Science chemistry students should take the equivalent of at least two additional laboratory or research courses, and biochemistry CHEM 351.

Of the 11 electives to be taken during the four undergraduate years, an additional mathematics course is desirable. Since science is an international enterprise, chemistry majors are encouraged to take a foreign language.

Students interested in coordinating graduate with undergraduate work should consult the department chair before the end of the sophomore year. The department offers a combined B.S./M.S. program for students who desire both more research and more advanced chemistry courses than are obtainable under the Bachelor of Science program. The B.S./M.S. program normally is elected in the sophomore year and is completed in the summer following the senior year.

Two minors are available in the department of chemistry:

The minor in chemistry requires six chemistry course credits. Only one of the course credits may be CHEM 160, CHEM 201, CHEM 202, CHEM 221, CHEM 222 or AP chemistry credit, toward a minor. The other five course credits must be numbered 211 or above and may include a maximum of one course credit of CHEM 375, CHEM 376, or CHEM 403.

The chemistry (biochemistry) minor requires six chemistry courses numbered 211 or above, including CHEM 351 and CHEM 352 and may include a maximum of one course credit of CHEM 375, CHEM 376, or CHEM 403.

Satisfying the disciplinary depth component of the College Core Curriculum:

Culminating Experience. Chemistry majors (B.S. and B.A.) will meet the Culminating Experience requirement in one of the following ways.

  • Carry out a research or independent study project in the chemical sciences and take CHEM 371, a 0.25-credit research seminar in the senior year. Each student enrolled in the research seminar will give a formal presentation on the research or independent study project that s/he has undertaken. The research or independent study component can be any one of the following: (i) at least one credit of undergraduate research (CHEM 375 or 376), (ii) A summer research project carried out either at Bucknell or elsewhere (research projects carried out elsewhere must have prior approval by the department), or (iii) an independent study project that involves some form of scholarly work in the chemical sciences other than a laboratory research project.
  • Take, during the senior year, one of the 0.5-credit special topics seminar courses (CHEM 385 or 386) that the department offers. These seminars apply principles that students have learned in their core chemistry courses to topics of current interest, and require each student to give a formal presentation.

Writing within the major. All chemistry majors are required to take either CHEM 340 (Biological Physical Chemistry) or CHEM 341 (Physical Chemistry I) which offer instruction in scientific writing and require students to write formal lab reports. The writing requirement can also be satisfied with CHEM 322, CHEM 332, or CHEM 342.

Formal Presentation Experience. Each of the ways in which B.A. and B.S. chemistry majors can satisfy the Culminating Experience requirement will require formal presentation(s) under the guidance of the research mentor or seminar course instructor.

Information Literacy. Any 0.5 or 1.0 credit chemistry course at the 300 level will satisfy this requirement.
