4 Cards in this Set
- Front
- Back
Ionic |
- Strong electrostatic forces - High melting point - Soluble in polar solvents, insoluble in non-polar - Conducts as a liquid or aqeuous solution |
|
Molecular |
- Strong intramolecular, weak intermolecular bonds - Low melting point - Polar molecules dissolve in polar solvents, vice versa - Never conduct - Solids shatter as only weakly held together |
|
Metallic |
- Found on LHS of periodic table - Very strong non-directional forces - High melting point - Never soluble - Conduct as solids and liquids - Can be shaped; non-directional forces |
|
Covalent Networks |
- Generally high melting point - Generally insoluble - Capable of conductivity - Come in 1D polymers, 2D sheets or 3D lattices. - Graphite is a covalent network: Can conduct and has weakly held together sheets of carbon atoms. |
