CIE IGCSE Coordinated Sciences C10: Metals

This revision pack includes clear, concise notes for all the content covered in C10 (Metals) according to the CIE IGCSE co-ordinated science new specification (new for the 2022 examinations).

The C10 topic includes:

• An understanding of the general physical properties of metals
• Metallic bonding, and how this can help to explain the electrical conductivity and malleability of metals
• Describing alloys, and understanding the difference in properties between alloys and pure metals
• Understanding the different types of steel (alloys of iron)
• The order of the reactivity series, and how this can be used to describe reactions of different metals with (i) water or steam, (ii) dilute hydrochloric acid, and (iii) the reduction of their oxides with carbon
• Reactivity series, illustrated by the reactions of metals with (i) aqueous ions of other metals, and (ii) the oxides of other metals
• The use of carbon in the extraction of certain metals from their ores, including a detailed understanding of the reactions in the extraction of iron from haematite in the blast furnace
• Understanding the extraction of aluminium from the ore bauxite using electrolysis
• Understanding metal ores as a finite resource and the need to recycle metals
• Aluminium: uses of aluminium, and the apparent unreactivity of aluminium
• The uses of mild steel and stainless steel
• The uses of zinc for galvanising steel and for making brass
