Here's a breakdown to help clear things up:
1. "Particles" can refer to:
* Atoms and Molecules: These are the building blocks of matter. Solids are made of atoms and molecules that are tightly packed together.
* Subatomic Particles: These are the particles that make up atoms (protons, neutrons, electrons). Solids, liquids, and gases all have atoms, and therefore subatomic particles.
2. "Solid" refers to a state of matter:
* Solids have a fixed shape and volume. The particles in a solid are held tightly together by strong forces, and they vibrate in place.
* Liquids have a fixed volume but not a fixed shape. The particles in a liquid are closer together than in a gas, but they can move around more freely.
* Gases have neither a fixed shape nor a fixed volume. The particles in a gas are far apart and move around freely.
So, what do particles have that solids don't?
* More freedom of movement: The main difference between particles in a solid and particles in a liquid or gas is their freedom of movement. Particles in a solid are locked in place, while particles in a liquid or gas can move around more freely.
* Less defined boundaries: While a solid has a clear and defined shape, particles in liquids and gases can take on the shape of their container.
In short, there's no single thing that "particles" have that "solids" don't. It's about the degree of freedom and arrangement of the particles.
