Bonding - Covalent
Cards in this deck (10)
- 1DefinitionShared pair of electrons between 2 atoms, both nuclei of atoms attracting that pair
- 2Dot + crossNo square brackets
- 3*Expansion of octet rule*Occurs from n=3, as larger capacity for electrons
- 4LatticeGiant covalent lattice
Non-metals forming network of strong covalent forces e.g. B/C/Si. - 5Mpt+BptHigh - strong covalent bonds make for a stable structure
- 6SolubilityInsoluble in almost all solvents - bonding too strong
- 7Electrical conductivityNon-conductors EXCEPT Graphene/'phite
- 8Carbon giant covalent structuresGiant covalent planar hexagonal layers w/ 120'
- 9Diff btw. 'phene 'phite'phene = single layer, extremely stong
'phite = Parallel stacks of layers w' weak London forces between. - 10Conductivity of graph' 'Delocalised e- free to carry charge.
