  • Ionic Bonding
    • Atoms can be made stable by transferring electrons-ionic bonding
    • Metal atoms lose electrons to get a stable structure
      • A positive ion is formed
    • During the bonding of MgO: Magnesium atoms lose two electrons to form positive magnesium ions
      • Oxygen atoms gain two electrons  to form negative oxide ions
    • Positive and negative ions are held together by attraction
    • The structure of MgO is a giant ionic lattice, in which positive ions have strong electrostatic attraction to negative ions
      • MgO has a high melting point because of the strong forces, cannot conduct electricity as a solid as the ions cannot move
