Recall that most metals are transition metals and that their typical properties include:

a) high melting point
b) high density
c) the formation of coloure
d) compounds
d) catalytic activity of the metals and their compounds

as exemplified by iron

Recall that the oxidation of metals results in corrosion

Explain how rusting of iron can be prevented by:

a) exclusion of oxygen
b) exclusion of water
c) sacrificial protection

Explain how electroplating can be used to improve the appearance and/or the resistance to corrosion of metal objects

Explain, using models, why converting pure metals into alloys often increases the strength of the product

Explain why iron is alloyed with other metals to produce alloy steels

Explain how the uses of metals are related to their properties (and vice versa), including aluminium, copper and gold and their alloys including magnalium and brass
