2.1 know that ionic bonding is the strong electrostatic attraction between oppositely charged ions
2.3 be able to describe the formation of ions in terms of loss or gain of electrons
2.4 be able to draw dot-and-cross diagrams to show electrons in cations and anions
Draw dot and cross diagram - Lithium fluoride
Draw dot and cross diagram - Magnesium chloride
Draw dot and cross diagram - Lithium Oxide
Draw dot and cross diagram - Calcium sulfide
Why do metals form positive ions, while non-etals form negative ions?
Use dot and cross diagram to show the electronic changes that occur during the reaction between calcium and fluorine.
Suggest why the strength of ionic bonding is greater in sodium fluoride than in potassium fluoride
Suggest why the strength of ionic bonding in calcium oxide is approximately four times larger than potassium fluoride
