Answer:
SiO₂(s) is an example of a network solid.
Explanation:
Network solids, also known as the covalent network solids, are the class of chemical compounds in which the constituting atoms are bonded covalently to form a continuous network, which extends through the material. In a network solid, there are no individual molecules and thus the whole solid is called a macromolecule.
Some of the examples of network solids are diamond and quartz.
Quartz or silicon dioxide is a three-dimensional continuous network of SiO₂ units.
