  • Diamond is a giant covalent structure consisting of only carbon atoms.
  • Diamond is made up entirely of covalently bonded carbon atoms.
  • Each carbon atom in diamond is bonded to four other carbon atoms by strong covalent bonds.
  • The structure of diamond is tetrahedral.
  • Diamond is very hard, the hardest material in the world, and has many industrial applications.
  • The carbon atoms in diamond form a rigid, extensive network with many covalent bonds.
  • Diamond has a very high melting point, around 4,000 degrees Celsius.
  • A lot of energy is required to break the strong covalent bonds in diamond.
  • Diamond cannot conduct electricity because there are no free charged particles.
  • In diamond, all outer electrons of carbon atoms are used in bonding, leaving no free electrons to move through the structure.
