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?

It shows that the atoms are vibrating in place.

Explanation:

In the crystal, the molecules exhibit a definite position, and they are combined with each other with the help of electrostatic forces. The molecules exhibit certain kind of energy due to which they vibrate in their locations. However, their energy is not that much high to result in overcoming the strong bonding, unless the atoms in the crystals are irradiated or are heated.
