atoms share pairs of electrons - usually occurs between non-metals - weak intermollecular forces so low MP and BP - insoluble in water - dont conduct
2 of 5
Ionic Bonding
atoms transfer electrons and form ions (held together by oppositley charged electrostatic forces of attraction) - usually between metals and non-metals - compounds are very strong, with high MP and BP -conduct when molten - a giant lattice structure
3 of 5
Covalent Bonding in Graphite
no covalent bonds between layers (only weak intermollecular forces) so layers can slide over one another - delocalised electrons mean it can acrry charge when other covalent structures cannot
4 of 5
Metallic Bonding
atoms pack together in large stuctures, with a regular pattern - strong electrostatic forces of attraction between negative delocalied electrons and positive ions
