- 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
