A network solid is a substance made up of an array of repeating covalently bonded atoms . ... Because of the way atoms are arranged, a network solid may be considered a type of macromolecule. Network solids may be either crystals or amorphous solids.
Is NaCl a network solid?
An example of an ionic solid is table salt, NaCl. ... Covalent-network (also called atomic) solids—Made up of atoms connected by covalent bonds; the intermolecular forces are covalent bonds as well. Characterized as being very hard with very high melting points and being poor conductors.
What is an example of a network solid?
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 SiO 2 units.

Why diamond is an example of network solid?
Diamond, for example, is a network solid. ... It forms covalent bonds with its neighboring atoms, sharing these electrons rather than exchanging them, but it forms an extended solid rather than individual units. Network solids are like molecules because they have covalent bonds connecting their atoms .
What are the 5 types of solids?
The main types of crystalline solids are ionic solids, metallic solids, covalent network solids, and molecular solids .
What are the 2 different types of solids?
Distinction between crystalline and amorphous solids . There are two main classes of solids: crystalline and amorphous.
What is an example of a covalent network solid?
Covalent Network Solids are giant covalent substances like diamond, graphite and silicon dioxide (silicon(IV) oxide) .
Which of the following is an example of covalent solid?
Silicon carbide is an example of a covalent solid.
Is graphene harmful to the human body?
At the level of the whole body, the authors indicate that there are two main safety factors to consider regarding exposure to CNTs and graphene. The first is their ability to generate a response by the body’s immune system ; the second is their ability to cause inflammation and cancer.
Is graphene flammable?
Graphene’s extremely high flammability has been an obstacle to further development and commercialization. ... For these reasons, graphene and similar two-dimensional materials hold great potential to substitute for traditional semiconductors.
How expensive is graphene?
However, as graphene currently ranges at anywhere between $67,000 and $200,000 a ton , there is a lot of potential to significantly reduce the cost of graphene products—perhaps, by even up to an order of magnitude.
Is ice a network solid?
– Ice is an ionic solid and it is also a molecule, so it cannot form a network solid.
What type of solid is diamonds?
Diamond is a network solid and consists of carbon atoms covalently bonded to one another in a repeating three-dimensional pattern. Each carbon atom makes four single covalent bonds in a tetrahedral geometry.
Is diamond is a covalent solid?
Diamond is a covalent solid and yet has a high melting point mainly due to its interlinked structure. Diamond crystallises in a lattice structure, indicating the presence of strong covalent bonds.
