Metals
________ until aluminium are extracted by electrolysis only while after carbon they can be extracted by reduction with carbon while after hydrogen, they can be extracted by reduction with hydrogen.
Sacrificial protection
The attaching of a more reactive metal with iron so it corrodes instead of iron, preventing rusting.
Alloys
Mixture of metals with some other element, usually another metal or carbon.
Pure metals
________ corrode far more easily than alloys.
time consuming
Recycling of metals is an essential process which conserves energy and resources, but is expensive and ________.
Reactivity series
The list of metals in order of decreasing reactivity.
presence of water
Rusting is the corrosion of the metal iron in ________ and air.
Metal
A solid material which is typically hard, shiny, malleable, fusible, and ductile, with good electrical and thermal conductivity.
Corrosion
A state of deterioration in metals caused by oxidation or chemical action.
Haematite
The raw core of iron which is refined into the metal iron.
Rusting
The corrosion of the metal iron in presence of water and air.
Recycling
The act of processing used or abandoned materials for use in creating new products.
