    Fire is not an element in itself (ie not a molecule/atom in gas/liquid form). Combustion requires an oxidant like Oxygen or Chlorine and it is a reaction that breaks down other molecules into combinations with the oxydant. Making steam if donor molecule contains Hydrogen, and CO2 if donor molecule contains carbon.
