Quick revision notes for The Solid State — Kerala Board Class 12 Chemistry. Key concepts, formulas, and definitions for last-minute revision.
Key Topics to Revise
1. Nature and Classification of Solids
- Solids have definite shape, volume, and are rigid due to strong intermolecular forces
- Particles vibrate about fixed positions with minimal kinetic energy
- Crystalline solids: Long-range order, sharp melting point, anisotropic properties
2. Types of Crystalline Solids
- Ionic Solids: Held by coulombic forces, hard and brittle, high melting points
- Molecular Solids: Van der Waals forces, soft, low melting points
- Covalent Solids: Covalent bonds, very hard, very high melting points
3. Close Packing and Crystal Structures
- Square close packing: Each sphere touches 4 others, less efficient
- Hexagonal close packing: Each sphere touches 6 others, more efficient
- HCP (ABAB): Hexagonal close packing, coordination number 12
4. Unit Cells and Crystal Lattices
- Unit cell: Smallest repeating unit that generates entire crystal
- Seven crystal systems: Cubic, tetragonal, orthorhombic, hexagonal, rhombohedral, monoclinic, triclinic
- 14 Bravais lattices: P (primitive), I (body-centered), F (face-centered), C (end-centered)
