4.6 properties of metal and non metals

  1. 1. WINTER Template 01 Are you ready to learn?
  2. 2. 02 4.6 PROPERTIES OF METALS AND NON-METALS
  3. 3. LEARNING OUTCOMES <ul><li>List examples of metals and non metals </li></ul><ul><li>List the properties of metals and non-metals </li></ul><ul><li>List the uses of metals and non-metals in daily life </li></ul><ul><li>Compare and contrast metals and non-metals based on their physical properties </li></ul><ul><li>Relate the physical properties of metals and non-metals to their uses in daily life </li></ul>03
  4. 4. METALS AND NON-METALS <ul><li>Elements can be classified into metals and non-metals, </li></ul><ul><li>All metals exist in solid state at room temperature except mercury (liquid) </li></ul><ul><li>Non-metals exist in solid liquid or gaseous state at room temperature </li></ul><ul><li>Examples of metals: Iron, aluminum , copper , lead </li></ul><ul><li>Examples of non metals : Carbon , Iodine , Bromine , Sulphur </li></ul>04
  5. 5. PHYSICAL PROPERTIES OF METALS AND NON-METALS <ul><li>Metals and non-metals can be differentiated by the following physical properties: </li></ul><ul><li>Luminosity : Shinny appearance </li></ul><ul><li>Ductility : Ductile can be stretched out like long wire </li></ul><ul><li>Malleability : Can be hammered or rolled into thin sheet </li></ul><ul><li>Tensile strength : Support pressure or load </li></ul>05
  6. 6. WINTER Template 06 ACTIVITY 1 : HANDOUT METALS DIFFERENCE NON-METALS Shiny surface Luminosity Dull surface Ductile Ductility Not ductile Rolled or hammered into thin sheet Malleability Cannot be forged High Tensile strength Low Good conductor Heat conductivity Poor conductor High Melting point and boiling point Low High Density Low Good conductor Electrical conductivity Do not conduct electricity except carbon
  7. 7. USES OF METALS AND NON-METALS IN DAILY LIFE 07 METAL PHYSICAL PROPERTY USE Iron High tensile strength Railways track Aluminum -Light -Good conductor of electricity and heat Kitchen utensils Copper Ductile and malleable Electrical wire Tin Does not rust Electroplating of food cans Gold Does not rust and shiny Jewellery Lead Ductile Malleable Cable casing
  8. 8. 08 NON-METAL PHYSICAL PROPERTY USE Carbon (graphite) -Soft and smooth -Good conductor -Lead of pencils -Electrodes in electrolysis and dry cells Carbon (diamond) -Hard Drill bits for cutting stone Neon gas and krypton -Poor conductor Lights used for billboards Chlorine -Acidic Kill germs in drinking water
  9. 9. EXERCISE / HOMEWORK 09 <ul><li>1) Give 2 examples each of metals and non-metals </li></ul><ul><li>2) Relate physical properties of metals to their uses </li></ul>Use of metal Physical property of metal Drawn out to become a long wire Material of I cent coin Making of cooking utensils Making of electric wire Making of bridges Making of jewellery
