The Reactivity Series
The Reaction of Metals with Air (Oxygen).
sodium, lithium, calcium and
react with oxygen and burn in air.
See the alkali metals and alkaline earth metals.
Metals in the reactivity series from aluminium to copper
react with oxygen in the air to form the metal oxide.
Aluminium is the fastest and copper is the slowest of the six.
Aluminium reacts quickly to form a surface layer
of aluminium oxide.
oxygen aluminium oxide.
4Al(s) + 3O2(g) 2Al2O3(s)
Zinc reacts fairly quickly to form zinc oxide.
zinc + oxygen zinc
2Zn(s) + O2(g) 2ZnO(s)
Iron reacts slowly at room temperature but quickly if it is heated.
iron + oxygen
oxide - see rusting.
4Fe(s) + 3O2(g) 2Fe2O3(s)
Metals below iron react with oxygen when they are heated in air.
tin + oxygen
2Sn(s) + O2(g) 2SnO(s)
lead + oxygen lead(II) oxide.
2Pb(s) + O2(g) 2PbO(s)
copper + oxygen copper(II)
2Cu(s) + O2(g) 2CuO(s)
Silver, gold and platinum do not react with oxygen in the air.
