Each pre-class Podia question is based on the pre-class material and working through the pre-class material will help you formulate your response. Consider the problem and write down/draw out your solution in your class notebook. These questions are designed to hone your skills so that you can analyze and solve mastery problems you will encounter throughout the course.
Two days before the next whole-class session, the pre-class Podia question will become visible in Podia, where you can click on the prompt and submit your answer.
Submissions for pre-class Podia activities are due 1 hour before the start of your whole-class. Be sure to submit your response before the due time.

What structural characteristics of an ionic compound influence its melting point? Use this list of characteristics to explain the differences in melting points in the compounds below. Provide reasoning using Coulomb’s law that links your model to your explanation.
- NaF: melting point = 996 °C
- KCl: melting point = 770 °C
