Learning Outcomes 

Students should be able to:


Properties of metals 

(a) describe the general physical properties of metals as solids having high melting and boiling points, being malleable and good conductors of heat and electricity 

(b) describe alloys as a mixture of a metal with another element, e.g. brass; stainless steel 

(c) identify representations of metals and alloys from diagrams of structures 

Reactivity series 

(a) place in order of reactivity calcium, copper, (hydrogen), iron, lead, magnesium, potassium, silver, sodium and zinc, by reference to the reactions, if any, of the metals with water, steam and dilute hydrochloric acid 

(b) deduce the order of reactivity from a given set of experimental results 

Extraction of metals 

(a) describe the ease of obtaining metals from their ores by relating the elements to their positions in the reactivity series  

Recycling of metals 

(a) describe metal ores as a finite resource and hence the need to recycle metals, e.g. the recycling of iron 

(b) discuss the social, economic and environmental issues of recycling metals 

Iron 

(a) describe and explain the essential reactions in the extraction of iron using haematite, limestone and coke in the blast furnace 

(b) describe the essential conditions for the corrosion (rusting) of iron as the presence of oxygen and water; prevention of rusting can be achieved by placing a barrier around the metal, e.g. painting; greasing; plastic coating
