- Bonding
- IONIC BONDING
- Definition = The loss of electrons to form positive ions
- Metal + Non Metal
- Loss of Electron = positive
- PROPERTIES
- High M and B points
- Strong electrostatic attraction
- Don't conduct when solid
- Ions aren't free to move and carry charge
- Conduct when molten or in solution
- Ions free to move and carry charge
- High M and B points
- Giant Lattice
- Ionic crystal
- 3 dimensional
- Electrostatic attraction
- Sodium chloride lattic
- Ionic crystal
- Higher charges = higher b.p
- COVELANT BONDING
- Definition = Sharing pairs of electrons to fulfill a full outer shell and become stable
- Non metal + Non metal
- PROPERTIES
- Low M and B points
- Weak intermolecular forces require little energy to break
- Do not dissolve in water
- Don't split ions
- Don't conduct electricity
- No free moving ions
- Low M and B points
- DIAMOND
- Tetrahedral
- Jewelry - refracts light
- Hard and strong - strong covelant bonds
- GRAPHITE
- Hexagon
- Strong covelant bonds
- Layers slide - weak intermolecular forces
- Carry charge - spare e
- High M and B points - strong covelant bonds
- METALLIC
- Definition = Giant lattice of positive ions, surrounded by a sea of delocalised e
- PROPERTIES
- Malleable
- Layers slide over eachother
- High M and B points
- Strong electrostatic attraction
- Conducts electrcity
- Free moving e
- Malleable
- IONIC BONDING
