- Giant Ionic structures
- Examples of Ionic Structures
- Sodium Chloride
- High Melting point (801 °C)
- Can't Conduct electricity when solid
- Can conduct electricity when molten liquid
- Can conduct electricity when Dissolved in water
- Magnesium Oxide
- Very high melting point (2850 °C)
- Can't conduct electricity when solid
- Can conduct electricity when molten liquid
- Can conduct electricity when Dissolved in water
- Not Very soluble though
- Sodium Chloride
- What is an Ionic Bond?
- Occurs between positive and negatively charged Ions
- Metals and non-metals
- The metals lose Electrons to have a stable structure
- Non-metals gain electrons to have a stable structure
- Occurs between positive and negatively charged Ions
- The structure
- The have strong electrostatic forces
- Because of the oppositely charged Ions
- Lots of energy needed to break the bonds
- Therefore have high melting and boiling points
- Solids at room temperature
- Cannot conduct electricity when solid
- Electrons are in fixed positions, and can't move around
- Can only vibrate in fixed positions
- Can conduct electricity when molten liquid
- Ions are free to move
- Allows them to carry an electrical charge
- Ions are free to move
- Some are able to dissolve in the water
- This is because the water molecules can split up the lattice
- Can conduct electricity when dissolved in water
- Allows them to carry an electrical charge
- Ions are free to move
- Can conduct electricity when dissolved in water
- This is because the water molecules can split up the lattice
- Has a structure of a Giant Lattice
- The have strong electrostatic forces
