(8, 7, 4) 6. made up of repeating monomers, linked together by strong covalent bonds to form a chain. (7) 7. These describe how atoms/ molecules interact in big groups. (4, 10) Down 2. can form four covalent bonds. (6) 3. giant covalent structure, which is hard due to a rigid structure. (7) 4. compounds formed by a reaction between metal and non-metal ions. (5, 8) 5. Allotropes that are shaped like a sphere and tube. (10) 8. sharing delocalised electrons between positive metal ions which gives the substance definite structure (8, 7) 9. Single layer of graphite. (8) 10. giant covalent structure, with lots of layers that can slide over each other. (8)
