I/GCSE Chemistry: Obtaining and Using Metals

Obtaining and Using Metals

· chemistry,igcse chemistry,IGCSE

Is the obtaining and using metals still on your minds from I/GCSE Chemistry?

Metals

Ores- are rocks which contain compounds of metal in them.

Reactive metals are found as compounds.

Non-reactive metals are found on their own-gold, silver and platinum

 

Examples of ores:

Extraction of Metals: 

This means removing whatever element is combined with the metal.

Usually the element is oxygen – so oxygen is removed.

Removal of oxidation is a type of reaction called reduction.

Addition of oxygen is oxidation- e.g burning, rusting

 

In I/GCSE Chemistry, there are two ways in which a metal can be ‘reduced’ or the oxygen is removed:

 

1. Heating with carbon
