WebA broad classification of solids in terms of their mechanical behavior would characterize them as brittle or ductile. While there is no doubt that ultimately this behavior is due to processes at the atomistic level, the link between these processes and their macroscopic manifestation is difficult to establish. WebFigure 1. The entities of a solid phase may be arranged in a regular, repeating pattern (crystalline solids) or randomly (amorphous). Metals and ionic compounds typically form ordered, crystalline solids. Substances that consist of large molecules, or a mixture of molecules whose movements are more restricted, often form amorphous solids.
WebAug 27, 2024 · Summary. The major types of solids are ionic, molecular, covalent, and metallic. Ionic solids consist of positively and negatively charged ions held together by … WebAug 14, 2024 · Ionic Solids. Figure 3. Sodium chloride is an ionic solid. Ionic solids, such as sodium chloride and nickel oxide, are composed of positive and negative ions that are held together by electrostatic attractions, which can be quite strong (Figure 3). Many ionic crystals also have high melting points.
