Network Solids
- Diamond is an example of a network solid
- Carbon atoms bond together with covalent bonds
- Diamond has a tetrahedral crystal shape
- Diamond is very hard (10 on the Moh's Scale of Hardness)
- To scratch diamond, you must break 1000s of strong covalent bonds
- To melt or boil diamond, you must break 1000s of covalent bonds
- Network solids are frequently used as abrasives because they are hard and have high melting points
