Answer:

Uses of Non-Metals in Daily Life

Many of the non-metals are present in the air we breathe and many of them are present in dry atmospheric air we see around us in volume percentage.

• Nitrogen which is present in 78% volume wise is an important element. This is used in industries for the production of ammonia which is an important ingredient of fertilizers we use in agricultural fields.

• Oxygen is another important element present in atmosphere and is present by volume 21% in the air. This is essential for life since it is required for respiration. Apart from respiration oxygen is also used in industries like manufacturing of steel, metal fabrication work where high temperature is required for the purpose. Oxygen cylinders are used in emergency situation and hospitals where this gas is used for trauma treatment.

• Noble gases like Argon, Xenon etc. are used in all kinds of colourful displays where glowing signs are utilised for advertisement purposes.

• Helium is used widely in all kinds of scientific research where the inert gas is made use of for specific environment .Helium is used by meteorology department for weather balloons.

• Light bulbs filled with Neon, Argon, Krypton are also made use of for producing laser beams .The Krypton, neon gases are used in filling night club bulbs to provide sparkling coloured bulbs for theatre and night clubs

• The Chlorine and Iodine are two other widely used non-metals and as they are present in group VII. Chlorine is used for purification of our drinking water supplies as it helps in killing the bacteria. Chlorine is also used as a bleaching agent which helps in removing stains or colour from various materials. Chlorine is used for making various useful chemicals like insecticides and graded plastics. Chlorine is also used for making polyvinyl chloride to be used in various pipeline and garden hose. Iodine is used widely as an antiseptic which prevents the growth of microorganism and used mainly to clean cuts and wounds. Iodine is also used for making anti-bacterial gurgles which helps in preventing throat infection.

• Carbon is unique among the elements in its ability to form strongly bonded chains, sealed off by hydrogen atoms. These hydrocarbons, extracted naturally as fossil fuels (coal, oil and natural gas), are mostly used as fuels.

• Impure carbon in the form of Charcoal (from wood) and Coke (from coal) is used in metal smelting. It is particularly important in the iron and steel industries.

• Graphite is used in pencils, to make brushes in electric motors and in furnace linings.
• Industrial diamonds are used for cutting rocks and drilling. Diamond films are used to protect surfaces such as razor blades.
