Non-metals are essential for our life. Non-metals like oxygen are used for respiration by living beings and for burning of fuels. Nitrogen is used for making ammonia which is an important constituent of fertilizers used for improving soil quality for crop production. Sulphur is used for making sulphuric acid and salts of metals. Hydrogen is used for making ammonia which is used for making fertilizers and as fuels in rockets. Chlorine is used to kill germs in water and iodine is used as an antiseptic as well as a disinfectant.
