C good conductors of both heat and electricity.
D not good conductors.
2. Which of the following statements is false?
A Copper is used as a roof covering because it can be made into sheets.
B Copper is used as a roof covering because it weathers to a green colour.
C Copper is used as a roof covering because it is quite light.
D Copper is used as a roof covering because it is a good conductor of electricity.
3 Which of these statements is true?
A An alloy is a metal element.
B An alloy is a metal compound.
C An alloy is a mixture of metals, or a metal and carbon.
D An alloy is a mixture of non-metals.
4 Which of these statements about using the particle model to describe the properties of alloys is false?
A It gives us a way of explaining why an alloy has different properties from the metals it contains.
B It gives us a way of predicting what might happen if we add different amounts of metal to an alloy.

the particle level inside an alloy. / Topic 2

C iron.
D magnesium.
3 Complete the word equation:
iron + oxygen ®

4 A copper coin is shiny when it is new, but will eventually go black and dull. The two words which best describe this process are:
A oxidation and neutralisation.
B corrosion and neutralisation.
C corrosion and reduction.
D oxidation and tarnishing
5. The gas which is given off when metals react with water is:
A carbon dioxide.
B hydrogen.
C oxygen.
D nitrogen.
6 Complete the word equation:
calcium + water ®
A calcium oxide + carbon dioxide
B calcium sulphate + oxygen
C oxygen + hydrogen
D calcium hydroxide + hydrogen
7 Look at these diagrams, and then choose the correct order of reactivity for metals X, Y and Z (the most reactive metal should be first).

A Z, X, Y
B. Y, Z, X
C. X, Y, Z
D. Z, Y, X
8 Reactive metals such as sodium, magnesium and calcium:
A have been known since ancient times because they do not join with other elements.
B are easily extracted from their oxides by heating with carbon which makes carbon dioxide.
C are extracted from their compounds using electricity to break the bonds.
D cannot be extracted from their compounds
because they are too reactive. / Topic 3
1 When iron corrodes:
A it evaporates into the air.
B it forms a protective layer on its surface.
C it reacts with chemicals in the environment
to form compounds.
D it turns green because it forms a coating of
copper carbonate.
2 Some window frames are made of a metal which
does not need to be painted, because it forms a
naturally protective layer. A metal which can be used
in this way is:
A copper
B PVC
C iron
D aluminium
3 Complete the word equation:
magnesium + sulphuric acid ®
A magnesium oxide + hydrogen
B magnesium oxide + sulphur dioxide
C magnesium sulphate + hydrogen
D magnesium sulphate + carbon dioxide
4 Which of these methods would not reduce the
corrosion rate of iron?
A painting it with gloss paint
B attaching it to a copper rod
C galvanising it (coating with zinc)
D plating it with a layer of tin
Topic 4
1 Which of these statements is true?
A Iron is more reactive than copper.
B Iron is more reactive than magnesium.
C Silver is more reactive than copper.
D Copper is more reactive than magnesium.
2 Magnesium reacts slowly with cold water,
but quickly with dilute acids. Calcium reacts quickly with water. Lead does not react with cold water and very slowly with acids. The order of reactivity, with the most reactive
first, is:
A magnesium, calcium, lead.
B calcium, lead, magnesium.
C magnesium, lead, calcium.
D calcium, magnesium, lead.
3 Zinc is less reactive than magnesium and
more reactive than lead. This means that zinc is likely to:
A react with acids but not with cold water
B react with cold water but not with acids
C react easily with cold water and with acids
D be unreactive with either acids or cold water.
4 Complete the word equation:
magnesium + hydrochloric acid ®
A magnesium oxide
B magnesium chloride + hydrogen
C magnesium hydroxide + chlorine
D magnesium chloride + oxygen
