Ionic Structure and Bonding

• Ionic Structure


  In an ionic compound, the ions are arranged in a giant ionic lattice
• Spaced-out view to make arrangement clear

  • Diagram showing spaced-out ions in a lattice
• But in reality it looks like this

  • Diagram showing close-packed ions in a lattice

  
• The ions alternate: + − + − etc.
• Ionic Bonding


  The electrostatic attraction between oppositely charged ions
• Ionic bonding is always a very strong attraction
