Unit 2. The Chemical Level of Organization
This unit is divided into 2 parts:
Part A: Basic Chemistry Chapter 2 Pages: pages 41-54
Part B: Organic Chemistry Chapter 2 Pages: pages 55-69
Part A: Basic Chemistry
1. Define: chemistry, biochemistry, matter, element, atom, atomic number, ,
isotope, atomic mass, atomic number, energy, work, chemical bond, chemical
formula, molecule, compound, solvent, solute, homogeneous, heterogeneous,
chemical bond, ion, cation, anion, salt, electropositive atom, electronegative
atom, polar covalent bond, nonpolar covalent bond, polar molecule, and chemical
reaction
2. Know the most abundant elements in the body including their chemical
symbols. Know the elements that belong to the second most abundant class
including their chemical symbols. Give examples of trace elements See table 2.1
3. Explain and diagram the structure of a electrically neutral atom : nucleus,
proton, neutron, electrons, electron shells, and valence shell
4. Define isotope. Explain how isotopes are similar and different to each other.
5. Explain the 2 forms of energy: kinetic and potential; Give an example of each
type
6. Explain and give an example of the 3 types of energy: chemical, electrical, and
electromagnetic energy. Give an example of each type
7. Define molecule and compound. Give an example of a molecule and
compound
8. Define isomer and their properties
9. Define mixture. Explain, with examples, the 4 types of mixtures: solution,
colloid emulsion, and suspension. Give an example of each type
10. List and describe the 3 ways to measure solute concentration: weight per
volume, percentage, and molarity
11. Explain the significance of the valence shell to the bonding properties of an
atom. Describe the valence structure of chemically reactive and chemically stable
elements
12. Compare and contrast the 3 types of chemical bonds: ionic, covalent, and
1
