| Question | Answer |
| Definition | Shared pair of electrons between 2 atoms, both nuclei of atoms attracting that pair |
| Dot + cross | No square brackets |
| *Expansion of octet rule* | Occurs from n=3, as larger capacity for electrons |
| Lattice | Giant covalent lattice Non-metals forming network of strong covalent forces e.g. B/C/Si. |
| Mpt+Bpt | High - strong covalent bonds make for a stable structure |
| Solubility | Insoluble in almost all solvents - bonding too strong |
| Electrical conductivity | Non-conductors EXCEPT Graphene/'phite |
| Carbon giant covalent structures | Giant covalent planar hexagonal layers w/ 120' |
| Diff btw. 'phene 'phite | 'phene = single layer, extremely stong 'phite = Parallel stacks of layers w' weak London forces between. |
| Conductivity of graph' ' | Delocalised e- free to carry charge. |
