physical properties of metals

  1. 1. PHYSICAL PROPERTIES OF METALS
  2. 2. METALS IN PERIODIC TABLE..
  3. 3. METALS
  4. 4. METALS HAVE MANY PHYSICAL PROPERTIES  Malleability  Ductility  Hardness  Metallic lustre  Thermal conductors  Electrical conductors  Sonority
  5. 5. MALLEABILITY  Metals can be beaten into thin sheets by hammering
  6. 6. GOLD IS THE MOST MALLEABLE METAL…
  7. 7.  One gram of gold can be beaten into sheets with an area of about 6.7 sq.ft
  8. 8. DUCTILITY  Metals can be drawn into thin fine wires 
  9. 9.  The filament of electric bulb made of fine wires of tungsten
  10. 10.  Platinum is the most ductile metal  Copper gold etc also used as thin wires..
  11. 11.  One gram of gold can be drawn into a wire of about 2km in length
  12. 12. HARDNESS..  Hardness is another property of metals  However there are quite a few metals which are soft.. Sodium Lithium Gallium Cesium Pottasium
  13. 13. METTALLIC LUSTRE  The surface of newly formed when metals are cut ,has shining appearance
  14. 14. THERMAL CONDUCTIVITY  The ability to conduct heat is an important property of metals
  15. 15.  Silver is the best thermal conductor among metals  Aluminium ,copper etc also possess comparatively high thermal conductivity
  16. 16. ELECTRICAL CONDUCTIVITY  The ability of metals to let electricity pass through it
  17. 17. SONORITY  The ability of metals to produce sound when tapped with a hard material
  18. 18. METALS CAN BE USED FOR MAKING..  Electric wires  Aluminium foils to wrap food materials  Utensils  Farming tools  Bells used in places of worship etc
