This document outlines syllabus statements from the Cambridge IGCSE Combined Science syllabus 0653 for exams from 2016 to 2018 regarding metals. It discusses properties of metals, reactivity series of various metals, and extraction of metals. Key points include distinguishing metals from non-metals by physical and chemical properties, placing metals in reactivity order, and relating extraction methods to reactivity series positions for certain metals like iron and copper.

2. 10.1 Properties of metals10.1 Properties of metals
1. Distinguish between metals and non-metals by
their general physical and chemical properties.
2. Identify and interpret diagrams that
represent the structure of an alloy.
3. Explain why metals are often used in the form
of alloys.

3. 10.2 Reactivity series10.2 Reactivity series
1. Place in order of reactivity: potassium, sodium,
calcium, magnesium, zinc, iron, hydrogen and
copper, by reference to the reactions (if any) of
the elements with:
•water or steam
•dilute hydrochloric acid (except for alkali
metals).

4. 10.2 Reactivity series10.2 Reactivity series
2. Compare the reactivity series to the tendency
of a metal to form its positive ion, illustrated by
its reaction, if any, with:
•the aqueous ions of other listed metals
•the oxides of the other listed metals.
3. Deduce an order of reactivity from a given set
of experimental results.

5. 10.3 Extraction of metals10.3 Extraction of metals
1. Describe the use of carbon in the extraction of
copper from copper oxide.
2. Describe the essential reactions in the
extraction of iron in the blast furnace.
3. Relate the method of extraction of a metal
from its ore to its position in the reactivity
series, limited to group I & II metals, aluminium,
iron and copper.
