Supersolids are strange materials that behave like both a solid and a fluid due to quantum effects – and now researchers have ...

Tell students that each salt crystal is made up of two different types of particles called sodium ions and chloride ions. Tell students that ions are atoms or molecules that have either a positive or ...

Each of these atoms carries an electrical charge—sodium ... This bond is the foundation of salt’s crystal structure. In a ...

The atoms and molecules that make up all substances ... a pattern that gives the crystal its special shape. Some crystals look very similar but here are a couple of ways to tell them apart. The salt ...

When a liquid metal cools and turns into a solid, its atoms come together to form crystals. The structure of these crystals is not perfect. Sometimes an extra layer of atoms squeezes between other ...
