Ionic Properties

• Ionic Properties


  Spec: 1.42-1.43, 1.56
• Ionic compounds


  • Have high melting points
  • Ionic bonds are very strong
  • In a giant ionic lattice there are lots of ionic bonds
  • Breaking all the ionic bonds requires a large amount of energy

  
• Some ionic compounds have higher melting points because their ions have higher charges
• Higher charges make the attraction between the ions even stronger and harder to break
• Electrical conductivity


  Requires charged particles that can move freely
• Ionic compounds conduct electricity

  1. Solid (s): No conductivity, Ions can't move freely

  2. Liquid (l) or dissolved (aq): High conductivity, Ions can move freely
