USES-OF-NONMETALS.pptx

  1. 1. NON-METALS uses OF SOME SCI 214 | INORGANIC CHEMISTRY PREPARED BY: ALJON F. FEGURASIN
  2. 2. Which of the non-metals are you familair with? Can you tell us its uses?
  3. 3. NON-METALS Nonmetals can be defined as the elements that form negative ions by accepting electrons from other elements. These elements are located at the upper right corner of the modern periodic table.
  4. 4. NON-METALS
  5. 5. List of Some Common Non-metals Non-metal Hydrogen Nitrogen Oxygen Fluorine Chlorine Bromine Iodine Carbon Sulphur (Sulfur) Phosphorous (Phosphorus) Silicon State at Room Temperature Gas Gas Gas Gas Gas Liquid Solid Solid Solid Solid Solid
  6. 6. N + 3H 2NH 2(g) 2(g) 3(g) • Hydrogen is used in manufacturing of ammonia gas which is further used in the manufacturing of urea (fertilizer). • Hydrogen is a constituent of many industrial fuels like water gas (CO + H2) and coal gas (H2 + CH4). Ammonia NON-METALS uses of some
  7. 7. • Carbon can be used to make pencils when it is in the graphite form. • Amorphous form of carbon, charcoal is used for ultrafiltration in modern water filters. Also, it is used in refrigerators to control bad odour. NON-METALS uses of some
  8. 8. N + 3H 2NH 2(g) 2(g) 3(g) • For the preparation of ammonia, and nitric acid, nitrogen is used. • Fertilizers contain nitrogen. It helps in plant growth. It enhances the rate of plant growth. Ammonia NON-METALS uses of some
  9. 9. • Oxygen which is 21% by volume helps in the respiration process. It is also used for the manufacturing of steel and provides high temperatures in the metal fabrication process. • Oxygen cylinders are used in hospitals. Si + O SiO (s) 2(g) 2(s) Quartz NON-METALS uses of some
  10. 10. • Chlorine is useful in removing stains and colour patches as a bleaching agent. Various graded plastics and insecticides are made with chlorine. It helps in the purification of water. Adding chlorine to drinking water kills the bacteria. • Helium is used as inert gas for scientific experiments. It is also used in weather balloons. • Bromine is used in the manufacturing of batteries, dyes, drugs and photography. Silver bromide is used for photography. NON-METALS uses of some
  11. 11. • Iodine helps to prevent throat infections and is used as an antiseptic on wounds and cuts. • Fluorine is critical for the production of nuclear material for nuclear power plants and for the insulation of electric towers. Hydrogen fluoride, a compound of fluorine, is used to etch glass. Fluorine, like Teflon, is used to make plastics and is also important in dental health. NON-METALS uses of some
  12. 12. Si + O SiO (s) 2(g) 2(s) • Silicon is used in making transistors, chips for computers and photovoltaic cells. • Silicon is used in steel industry to deoxidize steel and it produces high quality corrosion resistant steel. Quartz NON-METALS uses of some
  13. 13. P O + 3H O 2H PO 2 5 2 3 4 • Most of the phosphorous is used for making phosphoric acid (H3PO4) which is used in the manufacturing of phosphate fertilizers. • White phosphorous as (P4S3) is used in the match industry. • Phosphates are added to the detergents as they help in the removal of dirt from soiled cloths. Phosphoric Acid NON-METALS uses of some
  14. 14. NON-METALS • Sulfur is used in agriculture to control fungus and pests. • Sulfur is used in the manufacturing of gun powder which is an intimate mixture of sulfur, charcoal and potassium nitrate. • Most of sulfur is converted into sulfuric acid which is called the king of chemicals and is used to make variety of other chemicals. uses of some H S O + H O 2H SO 2 2 7 2 Sulfuric Acid 2 4
  15. 15. Why is it important to know and be familiar with the uses of non-metals?
