* Ionic bonds: These occur between oppositely charged ions, like in table salt (NaCl).
* Covalent bonds: These occur when atoms share electrons, like in diamond (C).
* Metallic bonds: These occur between metal atoms, where electrons are shared freely throughout the structure, like in copper (Cu).
These forces are stronger than the kinetic energy of the particles, which would normally cause them to move around freely. This means the particles are locked in a fixed, rigid structure and can only vibrate in place.
Here's a simple analogy: imagine a group of people holding hands tightly. They can still wiggle a little, but they can't move far apart because they are locked together.
Key takeaway: The particles in a solid are bound together by strong forces, preventing them from moving far from each other.
