2. The Reactivity Series Potassium Sodium Lithium Calcium Magnesium Aluminium Zinc Iron Tin Lead Copper Mercury Silver Gold Carbon Most reactive Least reactive 1.Which is most reactive, tin or calcium? 2.Why do gold and silver stay shiny? 3.Why is copper used for water pipes? 4.Why is potassium not used for bridges?

3. The Blast furnace What 3 solids go in? What goes in here? What comes out here and what is it’s use? What happens to the iron that is made? Why is limestone added to the blast furnace? What is this…? Fe 2 O 3 What is this…? CO What is this…? Fe What is this…? CO 2

4. Extraction methods Potassium Sodium Lithium Calcium Magnesium Aluminium Zinc Iron Tin Lead Copper Mercury Silver Gold Carbon Most reactive Least reactive High reactivity metals are extracted by… because… Medium reactivity metals are extracted by… because… Gold and silver are not extracted because… High reactivity metals were only discovered in the 20 th century because… Medium reactivity metals were discovered 1000s of years ago because..…

5. Metals key words Key wordMeaning Ore Native State Reduction Atom Alloy Transition metal

6. Aluminium and titanium Which words can be used to describe titanium and aluminium? Why is aluminium used for bicycles? Why is titanium used for jet engines? Why do aluminium and titanium not normally react? Why are aluminium and titanium so expensive?

7. Transition metals Label the transition metal part of the periodic table above. Name three transition metals PropertyMeaningPropertyMeaning High densityMalleable High melting point Ductile High conductivity Lustrous

8. Alloys iron atom carbon atom iron atom IronSteel What is an alloy? Use the diagrams to explain why steel is stronger than iron … Layers of atoms can slide

9. Displacement reactions Potassium Sodium Lithium Calcium Magnesium Aluminium Zinc Iron Tin Lead Copper Mercury Silver Gold Carbon Most reactive Least reactive A more reactive metal can displace a less reactive metal. e.g. magnesium + copper sulphate  magnesium sulphate + copper Finish these word equations: Iron + copper sulphate  Tin + copper chloride  Lithium + iron sulphate  Sodium + aluminium chloride  Sodium and magnesium are used to displace titanium from titanium chloride. What does this tell you about titanium?

10. Reduction reactions Potassium Sodium Lithium Calcium Magnesium Aluminium Zinc Iron Tin Lead Copper Mercury Silver Gold Carbon Most reactive Least reactive A metal which is less reactive than carbon can be extracted by reduction with carbon A metal which is more reactive than carbon, can only be extracted by electrolysis. What is a reduction reaction? Complete these word equations: Iron oxide + carbon  Lead oxide + carbon  Copper oxide + carbon  Iron oxide + carbon monoxide  How would you extract lithium?

11. Recycling Reasons for recycling metalsReasons against recyling metals Overall I think that metals should/shouldn’t be recycled because…
