1. How are protons, neutrons, and electrons involved in defining the element?  What is the difference between orbits and orbitals? 

2. Listen to this video about the states of matter (http://www.khanacademy.org/science/chemistry/states-of-matter/v/states-of-matter) (If the video does not play, paste the link in your browser.)  What did you learn about chemical bonds, states of matter, kinetic energy, density, heat, enthalpy, and other video topics?  How does this video relate to what Tro discusses?  How does this video apply to your job? How does it apply to your career?

3. Listen to this video about elements and atoms ( http://www.khanacademy.org/science/chemistry/introduction-to-the-atom/v/elements-and-atoms http://www.khanacademy.org/science/chemistry/introduction-to-the-atom/v/elements-and-atoms ).  (If the video does not play, paste the link into your browser.)  How does what the video says about water, elements, and atoms relate to what Tro (2011) discusses in Chapter 2 in the textbook?  What does what the video says about atomic number and isotopes relate to what Tro says in the textbook?  How does this video’s concepts relate to the workplace? How will your understanding of this affect your career?  (You only need to answer one of these questions to this question)
