CHEMISTRY ASSIGNMENT 20 point quiz in testing center (out of the total 420 points of the lecture section of A & P 1)Due Sept. 26, 2008 It may be completed before that date.

Chemicals are the foundation of life. Knowledge of basic chemistry is essential in order to understand physiology. The purpose of this assignment is to assess basic chemical knowledge. The assignment consists of suggested readings and activities followed by a quiz taken at the Testing Center located in the basement of the library. Many students have already taken chemistry or are taking it with A & P, so this should be a review. All students (especially those who never had chemistry) are welcome to visit Dr. Golz for extra help during her office hours in Room 2233.

You should know:1. The chemical symbol and atomic number for the following elements:

carbon hydrogen oxygennitrogen sodium chlorinepotassium calcium

2. The atomic structure (number of protons in the nucleus and number of electrons in each orbit) of the following: atoms of carbon, hydrogen, oxygen, nitrogen, sodium, chlorine molecule of hydrogen molecule of oxygen water carbon dioxide sodium chloride

3. The maximum number of electrons possible in the first three energy levels.

4. What is the reason for chemical bonds? How can you predict if two atoms will bond? How can you predict what type of bond will result? (ex: ionic or covalent)

Suggestions for study:.Human Anatomy & Physiology by Marieb (Textbook):Read pages 25 – 39. Most of the required information is here. Appendix: Periodic Table

Chemistry: An Introduction to General, Organic & Biological Chemistry by Timberlake (The Chem 105 Textbook)

Text: An Introduction to Chemistry for Biology Students by George Sackheim; publisher: Pearson Benjamin Cummings. ISBN number 0-8053-3970-1Paperback If you took CHM 105 at RCC, this book may have been included in the Chemistry Textbook.

If you have not had chemistry (or had it a while ago) it is strongly suggested that you use this book and answer the questions on the pages listed below. This is a “programmed learning’ workbook to help students learn or review basic facts, concepts, and terminology of chemistry that are essential to an understanding of biological phenomena. A copy of the book will be on reserve in the library under the name of Dr. Golz. You will not be able to write in this copy, but you should write the answers on a separate piece of paper. Price from Barnes and Noble (used) on line is about $17.00 - $20.00, available in 1 to a few days.

This book is also an excellent supplement to many other topics in A & P I, such as biochemistry (including DNA), osmosis, diffusion, active transport, nerve impulse, protein synthesis.

The following chapters are most important for understanding basic chemistry required to understand physiology.1. Inorganic Chemistry pages 3 – 18.2. Chemical Symbols pages 19 – 233. Atoms and Molecules pages 25 – 274. Ionization pages 29 – 428. The Covalent bond pages 101 – 11310. Functional Groups in Organic Compounds pages 125 – 139; 142-145

In addition, information is presented that supplements information in A&P 1 such as diffusion, osmosis, osmotic pressure, active transport, nerve impulse, DNA replication, protein synthesis.

Science Learning Center: CD: Biochemistry of Living Things is also recommended.Questions 1 – 13 on the quiz are taken from the post test on this CD.

When you are ready to take the quiz, go to the Testing Center in the Technology Center Building on the third floor. You will need photo ID. Tell the person at the desk that you want to take the quiz for Dr. Golz and she will give it to you. This is not an open book quiz. When you are done, submit the quiz to the person at the desk and it will be forwarded to me by campus mail. Call the Testing Center for the days and hours of operation. It is open Monday through Saturday during day and evening hours.

The quiz is composed of matching and multiple choice questions.
