Extraction of Non Metallic Elements:- non metallic elements are extracted from their combined states by oxidation. For example, halogens such as chlorine can be obtained by the oxidation of Cl-ions in water.

However, the oxidation of Cl-ions cannot be carried out by ordinary chemical methods. The oxidation of Cl- can be done by electrolysis. The minimum potential difference required for electrolysis process is 2.2 V. similarly; fluorine can be extracted by electrolysis.

Elements like oxygen, nitrogen and noble gases are present in air and can be isolated from it. Carbon, sulphur and phosphorus are extracted either from their native ores or by the oxidation from their compounds occurring in nature. However, there are no general methods of extraction of non metals and these are considered individually in different units.
