Network Solids


A network solid is a chemical compound where the atoms are bonded covalently in a continuous network. In a network solid there are no individual molecules and the entire crystal is the molecule.

Examples of network solids include diamond with a continuous network of carbon atoms and silicon dioxide or quartz with a continuous three dimensional network of SiO2 units. Graphite a consist of continuous two dimensional layers covalently bonded within the layer with other bond types holding the layers together.




Properties of network solids

Graphite- A 2-dimensional network solid is arranged in layers, with weak attractions between the layers. This makes them generally soft and/or slippery.

Diamond/quartz-A 3-dimensional network is a giant interlocking design, giving the substance exceptional hardness and a high melting and boiling point.
