For this unit, answer the following: 1. How is the electron configuration of an element determined? How do you know how many valence electrons an element has? (You may use nitrogen as an example element if it helps you explain.)
2. If nitrogen bonds with lithium, what kind of bond is it? How do you know? Draw or explain what Lewis dot diagrams would look like that show the electrons and how the compound would form. What
charge would the lithium have and what charge would the nitrogen have? What formula would the compound have? What would be its name?
3. Consider carbon. How many bonds can carbon make? If it makes a single bond with only chlorines(s), what
would the molecule look like? Draw a Lewis structure showing how the
bonding occurs. Name the molecule. What shape would it have? Would it be polar or nonpolar?
