Study Notes
Crystalline Solids
- Constituent particles are closely packed, enhancing stability and structural integrity.
- Individual particles are modeled as hard spheres to simplify analysis of their arrangement.
- Close packing of particles maximizes interparticle attractions, leading to lower energy states and increased density.
Coordination Number
- Defined as the number of neighboring spheres that touch a given sphere.
- Represents the level of compactness in close-packed structures—larger numbers indicate tighter packing.
- Coordination number is crucial for understanding the geometric arrangement and physical properties of different crystalline solids.
