Study Notes
Crystalline Solids
- A characteristic property of crystalline solids is their ordered arrangement of particles over a long range.
- Examples of crystalline solids include metals, ionic compounds, and some covalent compounds.
Amorphous Solids
- A characteristic property of amorphous solids is their lack of an ordered arrangement of particles over a long range.
- Amorphous solids do not possess an ordered arrangement over a long range.
Differences Between Crystalline and Amorphous Solids
- The main difference between crystalline and amorphous substances is the arrangement of particles: crystalline substances have an ordered arrangement, while amorphous substances do not.
- Examples of amorphous solids include glass, plastics, and gels.
Isomorphism and Polymorphism
- Isomorphism in the context of crystal structure refers to the phenomenon where two or more substances have the same crystal structure.
- Polymorphism in a substance refers to the existence of multiple crystalline forms of the same substance.
- Another term for polymorphism occurring in elements is allotropy.
- An example of isomorphous substances based on their atomic ratios is the pair of substances, CaCO₃ and MgCO₃, which have the same atomic ratio.
