Crystalline molecular solid
WebJan 20, 2024 · Molecular solids are crystalline solids in which lattice points are molecules which are held together by means of weak physical forces (van der Waal’s forces). In molecular solids, individual molecules are repeating units. Examples: Phosphorous, sulphur, chlorine and argon are molecular solids because lattice points are molecules. 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.
