DUE DATE: Wednesday, August 15, 2012 - at the
beginning of class
First AND Last name:
How are biological molecules necessary for organisms to grow, to reproduce, and to maintain organization?
How do the subcomponents of biological molecules determine the properties of that molecule?
Chapter 2 Objectives: The Chemical Context of Life
1. Define element and compound.
2. State four elements essential to life hat make up 99% of living matter.
3. Describe the structure of an atom.
4. Define and distinguish among atomic number, mass number, atomic weight, and valence.
5. Given the atomic number and mass number of an atom, determine the number of neutrons. Explain this process.
6. Explain why radioisotopes are important to biologists.
7. Explain how electron configuration influences the chemical behavior of an atom.
8. Explain the octet rule and predict how many bonds an atom might form.
9. Explain why noble gases are so unreactive.
10. Define electronegativity and explain how it influences the formation of chemical bonds.
11. Distinguish among nonpolar covalent, polar covalent and ionic bonds.
12. Describe the formation of a hydrogen bond and explain how it differs from a covalent or ionic bond.
13. Explain why weak bonds are important to living organisms.
14. Describe how relative concentrations of reactants and products affect a chemical reaction
