Chemistry:  The Core Concepts is an attempt to provide a rigorous but learner-friendly introduction to Chemistry. This textbook should serve the needs of science and non-science majors alike.

 1. The very first concepts are defined in simple terms that even someone with a minimal back­ground in science can understand

2. The order of presentation of topics is meticulously chosen so that sufficient background has been provided by the time each new concept is introduced

3. Examples are immediately provided to illustrate and/or apply each new concept

4. “Test yourself ” questions provide additional reinforcement; links to videos explaining the answers are provided

5. “Study resources” provide study tips and links to useful and interesting websites

6. Additional study questions provided in the companion website ( can be assigned as computer-graded homework

7. Useful physics and math background/review, often relegated to appendices in typical text­books, are integrated into the development of the topics.

 For alternative sequencing of topics (for a typical first-semester course), it is useful to organize the chapters into the following learning units: Unit 1: Introductory Concepts (Ch. 1–8) Unit 2: Atomic and Molecular Structure and Properties (Ch. 9–16) Unit 3: Counting Atoms, Molecules, and Ions (Ch. 17–20) Unit 4: Reactions in Aqueous Solutions (Ch. 21) Unit 5: Molarity and solution stoichiometry (Ch. 22) Unit 6: Ideal gas behavior and gas stoichiometry (Ch. 23–25) Unit 7: Real Gases, Liquids, and Solids (Ch. 26) Unit 8: Redox Reactions (Ch. 27) Unit 9: Solutions (Ch. 28) Unit 10: Thermochemistry (Ch. 29)Units 2, 3, and 4 may be covered in any order after Unit 1. Units 3 and 4 must be covered before Unit 5. Unit 3 must be covered before Unit 6 or 8. Units 2 and 6 must be covered before Unit 7. Units 5 and 6 must be covered before Unit 9.

The companion website,, is a web-based homework delivery and collection system, as well as a test bank authoring system and test generator. The automation afforded by i-Assign reduces a teacher’s workload while providing the following benefits: 

1. By setting periodic deadlines for graded homework, teachers are able to encourage students to study on a regular basis and focus on a manageable amount of material.

2. Teachers can set up practice homework to give students more opportunities for mastery.

3. Homework and test individualization minimizes cheating.

4. Teachers can add their own questions.

5. Multiple versions of a test, which can be printed or delivered online, can be easily generated.

About the Author(s): Glenn V. Lo

Dr. Glenn V. Lo is a Professor of Chemistry and Assistant Dean of the College of Arts and Sciences at Nicholls State University in Thibodaux, Louisiana. He has a B.S. in Chemistry (cum laude) from the University of the Philippines (1982), and a Ph.D. (Physical Chem­istry) from Kansas State University (1989). He did postdoctoral work at the Universite’ Joseph Fourier in France. His graduate work involved laser-induced fluorescence studies and spectral simulations. More recent research projects involved semiclassical dynamics simulations.  

Dr. Lo’s main interest is in improving science education. He has published in the Journal of Chemical Education and the Chemical Educator. In 1999, he co-developed an online homework system used by thousands of high school and college chemistry students worldwide. An improved version of the system is currently accessible at  Dr. Lo’s recent projects include a professional development program for high school physical science teachers (sponsored by the Louisiana Systemic Initiatives Program) and the development of video assessment library for Chemistry ( He is the director for the Region I tournament of the Louisiana science olympiad (http://, which serves New Orleans and surrounding parishes (counties).

 Dr. Michael A. Janusa received his B.S. from Louisiana Tech University in 1985 and a Ph.D. from Louisiana State University in 1993. He taught chemistry at Nicholls State University for ten years Austin State University in 2003. Dr. Janusa teaches General Chemistry, Inorganic, Analytical, and Environmental Chemistry. Known for his clear, well organized lectures, Dr. Janusa has received several awards for excellence in teaching. His research interest focuses on the environmental science area. He holds a U.S. patent in complexing heavy metals with bagasse (sugar cane by-product).
