Answer:
D. Atoms do not have empty spaces between them
Explanation:
That atoms do not have empty spaces between them is not part of the particle theory of matter. 
Here are some of the postulates of the theory; 
- A gas is composed of a large number of identical molecules moving at different speeds. 
- The space occupied by gas molecules is negligible compared to the volume of space they occupy. 
- The temperature of a gas is a function of their average kinetic energy.
