Ionic properties: Bonding structure and the properties of matter: Chemistry: (9:1)

• Giant ionic lattice


  A huge 3D regular structure held together by the electrostatic forces of attraction between positive and negative ions

  
• Melting and boiling points of ionic substances

  high
• Reason for melting and boiling points of ionic substances

  Strong electrostatic forces between opposite ions need lots of energy to break
• Movement of ions in a solid

  Ions vibrate around fixed positions
• Molten


  Made liquid by heat

  
• Movement of ions when molten

  Ions can move past each other

  
• Movement of ions in solution

  Ions break apart and move freely

  
• Conductivity of solid ionic compounds

  don't conduct

  
• Reason for conductivity of solid ionic compounds

  Ions are fixed in place

  
• Conductivity of molten/dissolved ionic compounds

  good conductors

  
• Reason for conductivity of liquid/dissolved ionic compounds

  Ions are free to move and carry charge

  
• Electrostatic force of attraction

  The attractive force between oppositely charged particles.
