There are VERY few giant covalent structures.
  • Diamond
  • Graphite
  • Silicon
  • Silicon dioxide

learn them ...

What about them?
Essentially just a giant structure that is formed due to ionic bonding. Electrostatic forces of attraction form between the oppositely charged ions.

Most compounds formed between a metal and another particle are made up of giant ionic lattices.

simple molecular substances as the name implies are made up of small molecules, they are mostly covalent in nature and will have low melting and boiling points, this means that they will be gases and liquids at room temperature or solids like wax or sugar that melt easily. Giant covalent structures will have high melting and boiling points, for example diamond, sand, glass all have giant covalent structures with very high melting and boiling points
