  1. State the properties of metals
    Strong

    Shiny

    Malleable

    Ductile

    Good conductor of heat

    Good conductor of electricity
  2. Where are metals located on the Periodic Table?
    The left hand side
  3. Name two metals and give a use for each
    Gold is used for jewellery

    Silver is used for cups and trophies
  4. State the properties of non-metals
    Soft

    Dull

    Low melting points

    Poor conductor of heat

    Poor conductor of electricity
  5. Where are non-metals located on the Periodic Table?
    The right hand side
  6. Describe how a metal reacts with water
    When an alkali metal eg. lithium is added to water it floats on the surface of the water

    Hydrogen gas is released

    This is an alkaline solution as it will turn red litmus paper blue and has a pH greater than 7

    The equation for this reaction is: Lithium + Water = Lithium Hydroxide + Hydrogen
  7. Describe how a metal reacts with oxygen
    When an alkali metal reacts with oxygen in the air it becomes dull and forms a metal oxide

    This is an alkaline solution as it turns red litmus paper blue and has a pH greater than 7

    The equation for this reaction is: Lithium + Oxygen = Lithium Oxide
  8. What is an alloy?
    It is a mixture of a metal and a non metal.  For example

    Bronze is a mixture of copper and tin

    Brass is a mixture of copper and zinc
  9. State two alloys and give a use for each
    Brass is used for candlesticks

    Bronze is used for statues and medals

    Steel is used for car bodies and bridges
  10. Explain what is meant by the reactivity series of metals
    This is putting the metals in order of their reactivity, from the most reactive to the least reactive
  11. Put the following metals calcium, zinc, magnesium and copper in order of decreasing reactivity
    Cats Make Zebras Cry

    Calcium

    Magnesium

    Zinc

    Copper
  12. Put the following metals calcium, zinc, magnesium and copper in order of increasing reactivity
    Cats Make Zebras Cry

    Calcium

    Magnesium

    Zinc

    Copper
  13. Define corrosion
    This is a chemical reaction when metals react with water and oxygen
  14. What is rusting?
    Rusting is a chemical change when iron joins with oxygen and water to form a new substance called rust
  15. List the conditions for rusting
    Oxygen

    Water
  16. State the ways a person can stop rusting from occurring
    Paint the metal

    Grease the metal with oil

    Cover the metal with a plastic coating

    Galvanising
