COURSE DESCRIPTION:
A systematic study of basic principles, laws and theories of modern chemistry. General topics covered are: measurement, atomic structure, formula names, periodic table of elements, chemical equations, chemical calculations and chemical bonding. Any mathematical skill needed beyond MATH 100 will be developed as part of this course.
THINKING SKILLS:
This course is designed to help the students to develop thinking skills that are needed to study chemistry. These skills include mathematical skills such as proportional reasoning as well as the skill to reason at the abstract level because so much of chemistry is abstract. In order to develop these scientific reasoning skills, the course content is presented in a three-part sequence. The first part involves observation of scientific phenomena. The second part involves term introduction and concept development. The third part is the application of the concepts just developed. Recent research indicates that all three stages are necessary for the development of thinking skills and a better appreciation of chemistry.
GENERAL COURSE GOALS:
- Introduce the students to the concepts and principles of chemistry.
- Develop the verbal and mathematical skills of the students so that they may accurately interpret and solve chemical problems.
- To prepare the students for more advanced courses in chemistry.
- To help students to develop thinking skills that is used in chemistry.
PERFORMANCE OBJECTIVES:
- At the end of this course, the student should be able to read, state and describe the meaning of certain scientific facts and concepts
- At the end of this course, the student should be able to solve simple chemical problems.
- At the end of this course, the student will be able to notice the differences between an orbit and an orbital, shell and sub shell, sub shell and an orbital, atomic number and atomic weight, orbital shape and orbital orientation.
- At the end of this course, the student will be able to write electronic configuration of any atom.
5.At the end of this course, the student will be able to demonstrate a working knowledge of the scientific method of investigation.
COURSE EXPECTATIONS:
Students are expected to attend all lectures, read the assigned materials, work individually to solve the assigned problems, take all the announced and unannounced quizzes, tests and the final examination. Students are expected to submit any work for grading in a timely manner. Any missed work must be completed and will be accepted only after evidence of appropriate excuse for missing the class.
MODES OF INSTRUCTION:
Instruction will include the following activities during the semester:
- Lecture and discussion
- Problem Solving
- Homework, quizzes and directed library research

- Examinations will include essay and short answer questions. Students should expect to write on examinations and to be able to write to the same standard as applies to the English Proficiency Exam in order to pass any examination that includes writing.
- All written work will be graded on quality and correctness, according to the EPE criteria for grammar, spelling, mechanics and organization.
- Plagiarism: It will be taken for granted that any work, oral or written, that a student does for this course is his/her original work. Any violation of this rule constitutes plagiarism. Plagiarism includes any unacknowledged/undocumented use of another’s writing or ideas, published or unpublished. A student who plagiarizes will receive an F for the project.
