Pearson Edexcel IAL Chemistry AS 3.4 Ionic crystal lattices
Pearson Edexcel IAL Chemistry AS 3.4 Ionic crystal lattices
Practise recognising ionic crystals as giant lattices and linking fixed or mobile ions to structure, bonding and conductivity.
How this is tested
- draw a sodium chloride lattice with alternating ions and a repeated giant ionic structure
- explain why solid ionic compounds do not conduct because their ions are fixed in position
- link molten ionic compounds to electrolysis by stating that ions are free to move
