This Podia problem is based on today’s pre-class material as well as material from previous days; working through that material will help you solve the problem.
Forces between atoms, ions, and molecules typically result in a graph of energy versus distance between particles that looks like this:
For each pair of substances listed below, make a graph of energy versus distance between atomic-scale particles. Use a single set of coordinate axes for each pair. Then draw a curve like the one above for each substance in the pair. Your curves should be to scale relative to each other, but there is no need to put values on the tick marks along the axes. The relative depths of the minima and the relative positions of the minima along the horizontal axis are important.
- NaCl and CaS
- CH4 and C6H14
- Cr and Cs
- Ne and CH4
Two days before the next whole-class session, this Podia question will become live on Podia, where you can submit your answer.
