Study Notes
- Different types of particles include unit cells, cations and anions, covalently bonded atoms, monoatomic or polyatomic molecules, and metallic ions in a sea of electrons.
- Interparticle forces include electrostatic, covalent, London, dipole-dipole, hydrogen, and metallic bonds.
- Hardness varies from soft to very hard, with some materials being brittle.
- Melting points vary widely, from very high to very low temperatures.
- Thermal and electrical conductivity varies among materials, with some being poor conductors in the solid state but good conductors when melted or dissolved in water.
- Exceptions to poor electrical conductivity include graphite, and diamond is a good conductor of heat.
- Examples of materials include NaCl, CaF2, diamond, silica, ice, benzoic acid, Na, Mg, and Cu.
