*** WHAT'S COVERED ***
1. The formation of ions
* How atoms gain or lose electrons to achieve a stable, full outer shell.
* Using equations to show the formation of positive and negative ions.
2. Ionic bonding explained
* The transfer of electrons from a metal atom to a non-metal atom.
* How oppositely charged ions are held together by strong electrostatic forces of attraction.
3. Dot and cross diagrams
* A visual method for representing ionic bonding.
* The key features of drawing these diagrams, including brackets and charges.
* How to draw diagrams showing only the outermost electron shells.
4. Worked example: Magnesium Chloride
* Step-by-step process for drawing the dot and cross diagram for the formation of magnesium chloride.
* How to represent a compound involving more than two atoms.
