Across
  1. 2. The elements in Group 7 of the periodic table. The halogens gain an electron to form halide ions with a 1- charge.
  2. 5. The forces which exist between molecules.
  3. 7. A giant covalent structure which is made up of carbon atoms, each of which form four covalent bonds with four other carbon atoms.
  4. 10. Molecules of carbon atoms with hollow shapes. Examples include Graphene and C60.
  5. 12. A giant covalent structure which is made up of carbon atoms each of which form three covalent bonds with three other carbon atoms.
  6. 13. Type of bonding between non metals.
  7. 14. Negatively charged subatomic particle.
Down
  1. 1. The type of bonding present in metals.
  2. 3. Elements that react to form negative ions. Found to the right of the periodic table.
  3. 4. An atom or molecule with an electric charge due to the loss or gain of electrons.
  4. 6. Elements that react to form positive ions. Found to the left of the periodic table.
  5. 8. The type of bonding formed between the oppositely charged ions when a metal atom loses electron(s) to form a positively charged ion and a non-metal gains these electron(s) to form a negatively charged ion.
  6. 9. A group of at least two atoms held together by covalent bonds.
  7. 11. A repeating regular arrangement of atoms/ions/molecules. This arrangement occurs in crystals.
