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