C1 Topic 4 Ores
Properties of metals
Copper
Conducts electricity
low reactivity
used in water pipes
Gold
Very unreactive
Conducts electricity
Aluminium
Used in aeroplanes
Doesn't corrode
Low Density
Iron
Soft
Cheap
Oxidation and Reduction
OIL RIG
Reduction
Gain in electrons
Loss in Oxygen
Oxidation
Loss of Electrons
Gain in Oxygen
Extracted by electrolysis
More reactive metals
More expensive
Recycling Metals
Advantages
Less Pollution
Less mining
Lasts Longer
Disadvantages
Cost
Some metals are expensive to recycle
Some are extracted by heating with carbon
Less reactive metals
Reactivity series depends on how they are extracted
Gold and platinum are natural found
The more reactive the more difficult to extract
