Materials in the solid state are generally categorized into two primary types based on their atomic arrangement:

: These have a highly ordered, repeating geometric pattern (a crystal lattice). Examples include salt (sodium chloride), diamonds, and most metals.

: It is very difficult to force the particles of a solid closer together. 11272mp4

: Strong internal bonds require significant energy to break, though this varies by material. Classification of Solids

A "solid" article of matter typically exhibits the following five characteristics: Materials in the solid state are generally categorized

: They possess "shear rigidity," meaning they resist deformation from external forces.

: They maintain their physical form regardless of the container. : Strong internal bonds require significant energy to

: These lack a long-range ordered structure. Their particles are arranged randomly, much like a "frozen" liquid. Common examples include glass, plastic, and rubber. Scientific Applications
