Chemistry Form 4: Chapter 5 - Ionic Bond

  • Ionic bonds are formed when valence electrons are transferred from a metal atom to a non-metal atom.
  • Metal atom releases valence electron to form positive ion in order to achieve stable noble gas octet electron arrangement.
  • Non-metal atom gains valence electron to form negative ion in order to achieve stable noble gas octet electron arrangement.
  • Positive ions and negative ions are held strongly by electrostatic force.
