1. Activity

a. What are you curious about?

b. Pre Activity Notes

1. Provide the electron configurations and Lewis Dot Diagrams for nitrogen, hydrogen, and iodine.
2. Do nitrogen, hydrogen, and iodine form an ionic or covalent bonds? Explain using Lewis Dots.
3. Which atom is larger, nitrogen or iodine? nitrogen or hydrogen? Explain.

c. Activity 4.1 (Covalent Bonds)

1. Make a model of Nitrogen Trihydride using balloons and tape.
2. Draw your model, to size, on one side of your whiteboard, labeling the atoms as either N or H.
3. Make a model of Nitrogen Triiodide using balloons and tape.
4. Draw your model, to size, on the other side of your whiteboard, labeling the atoms as either N or I.
5. Using your drawing, discuss why Nitrogen Trihydride is not explosive and Nitrogen Triiodide is very!
6. Insert a clear image your whiteboard, and summary of your description of your discussion here.
