Extracting metals Choosing methods for metal extraction. The position of the metal on the reactivity series determines the method of extraction. Higher placed metals (above carbon) have to be extracted using electrolysis as they are too reactive and cannot be reduced by carbon. Lower placed metals can be extracted by heating with carbon which ...

Specified Practical: Metal Displacement Reactions Introduction. The reactivity of metals decreases going down the reactivity series. This means that a more reactive metal will displace a less reactive metal from its compounds. Two examples are: Reacting a metal with a metal oxide (by heating) Reacting a metal with an aqueous solution of a metal ...

How do metals conduct electricity? Metals consist of giant structures. Within the metal lattice, the atoms lose their outer electrons and become positively charged metal ions. The outer electrons no longer belong to any specific metal atom and are said to be delocalised. Metals can conduct electricity because the delocalised electrons are able to move through the …
