- p-block elements gain one or more electrons to form stable anions.
- An ionic bond is the electrostatic force of attraction between oppositely charged ions.
- Millions of anions and cations pack together in a giant ionic lattice.
- Ionic bonding: strong electrostatic forces of attraction between oppositely charged ions(not atoms, not molecules) in a network.
Melting Point/Boiling point:
- Very strong forces of attraction, therefore a lot of heat is required to separate ions.
- IF you were to separate an ionic substance, you would need to break all the individual electrostatic bonds.
- However, they are very weak against force.
- The lattice simply shatters.
Properties of Ionic compounds:
-
Usually have high melting points.
-
Are often soluble in water, but there are exceptions (AgCl, BaSO4 etc.).
-
Always conduct electricity when melted or dissolved in water.
Solubility:
- Water is a universal solvent.
- It can only dissolve polar substances, and water itself is polar.
