Activity 5:  Guiding Questions

Answer the following questions using information gained through the readings, Thinkwell, CourseCompass, and websites.  Enter your answers and thoughts on the topics in your notebook.

  1. Explain the shell model of the atom and why it is used when discussing chemical reactions.
  2. Draw and label the subatomic particles that make up a carbon (C-12) atom and the particles that make up a C-14 isotope of carbon.
  3. Contrast the states of matter (solids, liquids, gases); atomic structure, atomic movement, pressure, and volume.
  4. How are molecules different than atoms?
  5. How is the periodic table organized?
  6. Why are valence electrons important in the formation of ionic and covalent bonds?
  7. Why does carbon tend to form covalent bonds?
  8. Why are some molecules polar and others nonpolar?
  9. Why is the law of mass conservation important in chemical reactions?
  10. How can you tell if a reaction classifies as an oxidation-reduction reaction?
  11. Why is oxygen a common oxidizing agent?
  12. How do catalysts affect chemical reactions?
