Hi! I use Khan Academy for SAT practice and other topics such as AP Chemistry. In school, we recently did lattice energy in chemistry, and wanted to see if there was a video on here. Unfortunately, there was not. I wanted to ask if it is possible for you guys to do video on lattice energy, as well as the Born-Haber cycle.

In fact, as a more general question, is there a way for us the suggest topics for future videos and articles to you guys on this website?
