Study Notes
Chemical Compounds and Bonds
- Compounds form when two or more elements chemically combine.
- Chemical bonds are the forces that hold these elements together.
- Bond length refers to the distance between the nuclei of two bonded atoms.
- Bond angle is the angle formed between two bonds connecting to the same atom.
Models Representing Molecules
- Ball-and-stick models depict atoms as balls and chemical bonds as sticks.
- Real chemical bonds are flexible, capable of bending, stretching, and rotating.
- Space-filling models illustrate the actual space atoms occupy within a molecule.
Structure and Properties of Compounds
- A compound's chemical structure significantly influences its properties.
- Compounds with network structures, such as quartz, tend to be strong solids.
- Quartz consists of silicon dioxide (SiO₂), where each silicon atom is bonded to four oxygen atoms.
Types of Bonds and Interactions
- Network structures may consist of bonded ions or molecules.
- The strength of attraction between molecules can vary, affecting the physical characteristics of compounds.
