Covalent network

Question 1

What is a covalent network

Answer 1

Large three dimensional network of covalently bonded atoms

Question 2

Properties

Answer 2

High melting point (covalent bonds that hold atoms together are strong electrostatic)
Do not conduct electricity (no charged particles)
Hard and brittle (strong intermolecular forces)
Insoluble in water (no attraction between the atoms in the network)
