Study Notes
Types of Solids
- Polycrystalline solids consist of many small crystals or grains.
- Crystalline solids feature a regular, periodically repeated structure of atoms.
- A crystalline solid can be described as an ordered array of atoms bound by electric forces, exhibiting strong interatomic interactions.
- The term "long-range order" refers to the arrangement of atoms in a crystal that extends throughout the entire sample.
Characteristics of Different Solids
- Amorphous solids are characterized by atoms that lack long-range order, leading to a more random arrangement.
- Atomic structure in crystalline solids provides distinct properties like fixed melting points and uniformity, unlike amorphous solids which may have variable properties.
