Study Notes
- Solid state of matter has strong interparticle forces of attraction, resulting in definite shape and volume.
- Smallest constituent particles of solids are atoms, ions, or molecules.
- There are two types of solids: crystalline and amorphous.
- Crystalline solids have regular and periodic arrangement of particles, sharp melting points, and anisotropic properties.
- Amorphous solids have randomly arranged particles, no sharp melting points, and isotropic properties.
- Isomorphism refers to substances with the same crystal structure and atomic ratio.
- Polymorphism refers to a single substance existing in two or more forms or crystalline structures.
- Crystalline solids are classified into ionic, covalent network, molecular, and metallic solids.
- Ionic crystals have charged ions held by electrostatic force of attraction, are hard and brittle with high melting points, and nonconductors in solid state but good conductors when melted or dissolved in water.
- Examples of ionic crystals include NaCl, K2SO4, CaF2, and KCl.
