What to Focus On

  • Solids have definite shape and volume.
  • Constituent particles are closely packed with strong intermolecular forces.
  • Particles vibrate about fixed positions but do not move freely.

  • Crystalline solids: long-range order, sharp melting point, anisotropic.
  • Amorphous solids: short-range order, no sharp melting point, isotropic.
  • Crystalline solids have well-defined faces and interfacial angles.

  • Ionic solids: ions, coulombic forces, high melting point.
  • Molecular solids: molecules, van der Waals forces, low melting point.
  • Covalent solids: atoms, covalent bonds, very high melting point.

Common Mistakes to Avoid

All solids with a definite shape are crystalline.

Hexagonal close packing (hcp) and cubic close packing (ccp) are the same because both have coordination number 12.

In a face-centered cubic (fcc) unit cell, atoms at face centers belong entirely to that cell.

Memory Tips

Classification of solids: Crystalline vs Amorphous

Types of crystalline solids: Ionic, Molecular, Covalent, Metallic

Properties of ionic solids: High melting point, hard and brittle

Coordination number in close packing: 12 for both HCP and CCP
