ASSIGNMENT: Science Blog: How Atoms Bond (10 points)

This Week's Science Blog Topic: For this week's blog entry watch the video below and answer the questions that follow. 

• What determines whether two atoms bond covalently or ionically?

• Choose a molecule from the video, and write a complete and correct Lewis structure for it. What information (about protons, neutrons, and electrons) gets transferred from the full view we show in the video to the Lewis structure? Why do you think Lewis structures are a useful tool for chemists?

• Explain how human chromosome 13 can be composed of just two molecules but have so many atoms. What are those two molecules?
  

Blog Guidelines: 

• Each blog post should be at least one paragraph (3-5 sentences minimum).
