Study Notes
Physical States of Matter
- Matter can exist in three physical states: solid, liquid, and gas
- Solids have definite volume and shape, and are different from liquids and gases
General Characteristics of Solids
- Solids have strong cohesive forces holding their atoms, ions, or molecules together
- Solids are rigid and incompressible
- Solids have short interatomic, ionic, or molecular distances
- Solids have constituents (atoms, ions, or molecules) with fixed positions, which can only oscillate about their mean positions
Classification of Solids
- Solids can be classified into two major types: crystalline solids and amorphous solids
- Crystalline solids have a regular arrangement of their constituents
- Examples of crystalline solids:
- Ionic crystals (e.g., NaCl, KCl)
- Covalent crystals (e.g., Diamond, SiO2)
- Molecular crystals
- Metallic crystals (e.g., all metallic elements like Na, Mg, Cu, Au, Ag)
- Atomic solids (e.g., elements of Group 18)
- Amorphous solids have an irregular arrangement of their constituents
- Examples of amorphous solids:
- Glass
- Rubber
