- Bonding Structure and Properties
- Covalent bonding is a shared PAIR of electrons
- Simple Molecular e.g. Water
- Do not conduct electricity
- Low MPT + BPT
- Doesn't dissolve in water
- Weak intermolecular forces
- No free electrons
- Giant Covalent
- Graphite
- Soft and Slippery
- Doesn't Dissolve in water
- High MPT
- Delocalised electrons between layers
- Conducts electricity
- 2-D layer structure with WEAK intermolecular forces
- Diamond
- High MPT
- Hard
- Does NOT conduct electricity
- 3-D great structure
- Graphite
- Simple Molecular e.g. Water
- Metallic bonds have attractions between metal CATIONS+ sea of delocalised outer electrons
- Doesn't dissolve in water
- Layers can slide over each other
- Malleable + ductile
- Strong attractive forces between metal cations and 'sea of electrons'
- High MPT
- Conduct electricity
- Free delocalised electrons that carry the current
- Ionic bonding is the attraction between positive + negative IONS
- Giant Ionic e.g. NaCl
- Soluble in water
- High MPT
- Conducts electricity when liquid
- Giant Ionic e.g. NaCl
- Covalent bonding is a shared PAIR of electrons
