Here’s a explanation:
Crystalline Solids
- Definition: Solids in which particles are arranged in a regular, repeating pattern called a crystal lattice.
- Properties:
- Definite shape and sharp melting point.
- High degree of order and symmetry.
- Examples: Salt, diamond, sugar.
Amorphous Solids
- Definition: Solids in which particles are arranged randomly, without long-range order.
- Properties:
- No definite shape and soft melting over a range of temperatures.
- Less rigid structure.
- Examples: Glass, rubber, plastic.
Key Difference in One Line:
- Crystalline: Ordered structure, sharp melting point.
- Amorphous: Disordered structure, melts gradually.
In short: Crystalline solids have regular, repeating particle arrangements, while amorphous solids are irregular and lack long-range order.
