Welcome to Module 2

Welcome to Week 2.

Chapter 2 covers the Chemistry of Life. This chapter covers some basic concepts concerning the organization of the atom, chemical bonding, acids and bases, the properties of water, and why water is necessary to support life.

For this chapter, you will read Chapter 2, complete the Chapter 2 homework assignment, Dynamic Study Module, and lab assignments on Acid and Bases.

Please follow the due dates in your syllabus and the late assignment policies.

As always, if you have any questions, please do not hesitate to contact me.

Sincerely,

Dr. Burke

Module Learning Outcomes

Upon successful completion of this module, you will be able to:

2.1 Define matter, an element, a compound, and a trace element.

2.2 Explain how and why iodine, fluoride, and iron are added to the human diet.

2.3 Distinguish between the size, location, and properties of protons, electrons, and neutrons.

2.3 Define the atomic number and mass number of an atom.

2.3 Define an isotope and explain what makes some isotopes radioactive.

2.4 Describe the uses and dangers of radioactive isotopes.

2.5 Explain how the electron configuration of an atom influences its chemical behavior.

2.6–2.8 Distinguish between covalent bonds, nonpolar polar covalent bonds, polar covalent bonds, hydrogen bonds, and ionic bonds, noting their relative strengths and how and where they form.

2.9 Explain the significance of chemical reactions. Identify the reactants and products of photosynthesis.

2.10–2.13 Describe the special properties of water that make it vital to living systems.

Explain how these properties are related to hydrogen bonding.
