What is solid matter11/9/2023 Crystalline Solid: Particles in a crystalline solid are arranged in a regular lattice.Solids may be categorized as crystalline, polycrystalline, or amorphous. There are different ways to classify solids. Most chemical elements (exceptions include many nonmetals)Įxamples of things that are not solids include air, water, liquid crystals, the elements mercury and helium, and steam.Gems and most crystals (diamond, sapphire, ruby).Everyday objects (pots and pans, desk, toys, computer, automobile).Building materials (bricks, wood, glass, concrete).Most metals (coins, tools, cutlery, nails).This allows atoms and molecules to form chemical bonds.Īnything with a fixed shape and volume is an example of a solid. Particles are packed closely together.The arrangement may be a regular lattice called a crystal or an irregular arrangement called an amorphous solid. The particles in a solid (atoms, molecules, ions) are tightly-packed compared to liquids and gases. In contrast, liquids can change shapes, while gases can change both shape and volume. Because its particles are packed close together, a solid is rigid, doesn’t flow, and isn’t easily compressed.Ī solid is defined as a state of matter with a definite shape and volume. This entry was posted on Octoby Anne Helmenstine (updated on May 2, 2021)Ī solid is matter that has a defined shape and volume.
