Edexcel IGCSE Chemistry 2017 Ionic bonding 2

This video covers the following specification points from the Edexcel IGCSE Chemistry 2017 specification:

1.40 Draw dot-and-cross diagrams to show the formation of ionic compounds by electron transfer, limited to combinations of elements from Groups 1,2,3 and 5,6,7
Only outer electrons need be shown
1.41 Understand ionic bonding in terms of electrostatic attractions
1.42 Understand why compounds with giant ionic lattices have high melting and boiling points
1.43 Know that ionic compounds do not conduct electricity when solid, but do conduct electricity when molten and in aqueous solution
