2.22C Metal ores and native metals

Know that most metals are extracted from ores found in the Earth’s crust and that unreactive metals are often found as the uncombined element

2.23C Extraction method and reactivity

Explain how the method of extraction of a metal is related to its position in the reactivity series, illustrated by carbon extraction for iron and electrolysis for aluminium

2.24C Evaluating metal extraction processes

Be able to comment on a metal extraction process, given appropriate information detailed knowledge of the processes used in the extraction of a specific metal is not required

2.25C Uses of aluminium, copper, iron and steel

Explain the uses of aluminium, copper, iron and steel in terms of their properties the types of steel will be limited to low-carbon (mild), high-carbon and stainless

2.26C Alloys

Know that an alloy is a mixture of a metal and one or more elements, usually other metals or carbon

2.27C Why alloys are harder

Explain why alloys are harder than pure metals
