Full Answer
What is network solid and what are some examples?
The covalent bonding lends network solids characteristic properties:
- Generally insoluble in any solvent
- Very hard
- High melting point
- Low electrical conductivity in the liquid phase
- Variable electrical conductivity in the solid phase (depends on bonding)
Which substance is an example of a network solid?
What are the 10 properties of solid?

- Malleability and ductility.
- Melting point.
- Solubility.
What is an example of a network solid?
These include:
- Liquid crystals: A liquid crystal is intermediate between a liquid and solid.
- Superfluid: A superfluid is like a liquid, but with zero viscosity.
- Bose-Einstein condensate: Bose-Einstein condensate is like a super-cold gas in which particles stop behaving independently of each other.

Which is an example of a network solid?
One common examples of network solids are diamond (a form of pure carbon) Carbon exists as a pure element at room temperature in three different forms: graphite (the most stable form), diamond, and fullerene.
What substances are network solids?
Covalent Network Solids are giant covalent substances like diamond, graphite and silicon dioxide (silicon(IV) oxide).
Is ice an example of network solid?
- Ice is an ionic solid and it is also a molecule, so it cannot form a network solid.
Is Ain an example of network solid?
(a, b, c) SiC, AIN and diamond are examples of network solid as they have three dimensional structure while, I; is a molecular solid, because such solid particles are held together by dipole-dipole interactions.
Is NaCl a network solid?
Ionic solids—Made up of positive and negative ions and held together by electrostatic attractions. They're characterized by very high melting points and brittleness and are poor conductors in the solid state. An example of an ionic solid is table salt, NaCl.
Is graphite a network solid?
Three-dimensional network solids (such as diamond or silica) are hard and rigid, whereas two-dimensional network solids (such as graphite) are soft due to the ease with which the network layers can slide past each other.
Is h20 a network solid?
Which of the following is a network solid? (a) SO2 (solid) (b) I2 (c) Diamond (d) H2O (ice) Answer: (c) Diamond is a giant molecule in which constituent atoms are held together by covalent bond.
Is SiO2 a network solid?
Silicon dioxide, SiO2 is a crystalline network solid, generally known as “quartz” or “silica”, is made up of polar covalent interaction between elements silicon and oxygen. Much of these elements are found in the earth's crust in the form of silicon dioxide.
Is silicon carbide a network solid?
Silicon Carbide (SiC) is a covalent network solid. If we look at its structure, we will find the atoms of silicon are joined together with carbon atoms with the help of a covalent bond tetrahedrally.
Is P4 a covalent network solid?
P4 molecule is a molecular solid which is a polymer.it is a molecular solid as the constituent particles in the solid are P4 molecules.
