Across
  1. 4. A giant covalent structure which is made up of carbon atoms each of which form four covalent bonds with four other carbon atoms.
  2. 7. A repeating regular arrangement of atoms/ions/molecules; this arrangement occurs in crystal structures.
  3. 9. Molecules of carbon atoms with hollow shapes. The structures are based on hexagonal rings of carbon atoms but they may also contain rings with five or seven carbon atoms.
  4. 10. The strong forces of attraction between oppositely charged ions.
  5. 11. A repeating regular arrangement of atoms/ions/molecules. This arrangement occurs in crystal structures.
  6. 12. An atom or molecule with an electric charge due to the loss or gain of electrons.
Down
  1. 1. A shared pair of electrons between two non-metals.
  2. 2. Large long-chain molecules made up of lots of small monomers joined together by covalent bonds
  3. 3. The forces which exist between molecules.
  4. 5. A single layer of graphite with properties that make it useful in electronics and composites.
  5. 6. Chemical compound formed of ions, held together by strong electrostatic forces.
  6. 8. A giant covalent structure which is made up of carbon atoms each of which form three covalent bonds with three other carbon atoms, forming layers of hexagonal rings which have no covalent bonds between the layers.
