Classroom Considerations
  • Relies on prior knowledge from the previous videos in the series
Pros
  • Provides prompts to get out paper and pencil as well as pausing the video to solve practice problems
  • Includes a reminder that ions are stable as long as their outer electron shells are full, not just if the outer shell has eight electrons
Cons
  • None
