Particles are always in motion, however, some more than others (see for instance gases vs liquids vs solids).

The idea in chemistry is, that there are three degrees of freedom:

  1. Vibration
  2. Rotation
  3. Translation (movement through space)

Solids: Only can only vibrate
Liquids: Vibrate, Rotate and have limited Translation
Gases: Can display all three degrees of freedom

The only instance at which there would be no motion is at absolute 0. But this is a whole other story.
