WebJan 29, 2024 · Crystalline solids are the most common type of solids, whose structure consists of a regular, repeating pattern of atoms or molecules in three dimensions. There are four different types of crystalline solids, all with different properties: ionic, covalent network, metallic and molecular. 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.

Constituent particles in ionic solids of the Crystalline Solids are anions (negatively charged) and cations (positively charged). An ion is surrounded by a typical number of opposite charges. For example, in NaCl, the Na+ ion is surrounded by 6 Cl- ions. Ions in these solids are held together by strong electrostatic forces. northgate village apartments bossier city la
