metals

• There are 3 methods of extraction

  Displacement, extraction, electrolysis
• Displacement is when the metal has a lower ionisation energy than the element being displaced.
• the most reactive metals use electrolysis as a method of extraction
• the most reactive metal is potassium
• The least reactive metal is gold
• zinc, carbon, iron and lead are all metals that can be displaced using carbon
• what metals can be displaced with carbon?


  Zinc, carbon, iron and lead
• alloy

  A mixture of metals, or a mixture of one or more metals with a trace amount of a non-metal (typically carbon).
• steel is an example of an alloy
• alloys have different properties to pure metals.
