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.
