Gerry is looking at salt under a powerful microscope and notices a crystalline structure. What can be known about the salt sample that Gerry is looking at?

Salt is a crystalline solid, so its particles are arranged in an orderly pattern and stay in fixed positions. They can still vibrate in place, but they do not spread out or slide past one another. Therefore, the salt’s atoms are vibrating in place.
