Chemistry 253
This course is intendedprimarily as an introduction course to materials and solid state chemistry forgraduate students and advanced undergraduate students. The objective is tounderstand solids from a chemical perspective and introduce general solid statesynthesis methodologies and characterization techniques. Topics covered willinclude: structure and structure determination of crystalline solids; freeelectron model for metals; electronic band structure; chemical bonding insolids; structure-property relationships.

- To understand the correlation between bonding and the properties of solids.
- To classify solids as ionic, molecular, covalent (network), or metallic, where the general order of increasing strength of interactions.
Type of Solid | Interaction | Properties | Examples |
---|---|---|---|
Ionic | Ionic | High Melting Point, Brittle, Hard | NaCl, MgO |
Molecular | Hydrogen Bonding, Dipole-Dipole, London Dispersion | Low Melting Point, Nonconducting | H2, CO2 |
Metallic | Metallic Bonding | Variable Hardness and Melting Point (depending upon strength of metallic bonding), Conducting | Fe, Mg |
Network | Covalent Bonding | High Melting Point, Hard, Nonconducting | C (diamond), SiO2 (quartz) |

Carbon: An example of an Covalent Network Solid
- What is the bonding geometry around each carbon?
- What is the hybridization of carbon in diamond?
- The diamond structure consists of a repeating series of rings. How many carbon atoms are in a ring?
- Diamond are renowned for its hardness. Explain why this property is expected on the basis of the structure of diamond.
- What is the bonding geometry around each carbon?
- What is the hybridization of carbon in graphite?
- The a layer of the graphite structure consists of a repeating series of rings. How many carbon atoms are in a ring?
- What force holds the carbon sheets together in graphite?
- Graphite is very slippery and is often used in lubricants. Explain why this property is expected on the basis of the structure of graphite.
- The slipperiness of graphite is enhanced by the introduction of impurities. Where would such impurities be located and why would they make graphite a better lubricant?
