Question

What are network solids? Give an example.

Hint:

Network solids are characterized by their strong covalent bonds and extensive, continuous networks.

Answer 1

Step 1: Definition of Network Solids.
Network solids are a class of solids where the atoms are bonded together in a continuous network, extending throughout the material. The atoms are connected by strong covalent bonds, forming a giant structure with no distinct molecules. These solids tend to have high melting points, are generally hard, and are poor conductors of electricity.
Step 2: Example.
A common example of a network solid is diamond, where each carbon atom is covalently bonded to four other carbon atoms in a tetrahedral arrangement, forming a three-dimensional network. Other examples include quartz (SiO₂) and graphite.
