- Ionic bonding
- Between a metal and a non-metal
- Atoms loose or gain electrons to form ions
- Full outer shell
- Structure of nobel gas
- Electrically charged
- Full outer shell
- Electrostatic attraction between positive and negative ions
- Atoms loose or gain electrons to form ions
- Substances conduct electricity when molten
- The ions are free to move in the liquid state
- Ions have a charge
- Or ionic compounds which are soluble in water
- The ions are free to move in the liquid state
- eg.
- Brittle
- When the lattice is hit, a layer of ions is shifted
- Like charges are lined up, they repel and shatter the lattice
- When the lattice is hit, a layer of ions is shifted
- Ions
- Metals form +'ve ions
- Non-metals form -'ve ions
- Metals form +'ve ions
- Usually soluble in water
- No intermolec. forces
- High melting and boiling points
- Form giant molecular structures
- (NaCl)
- (MgO)
- Between a metal and a non-metal
