2. 02 4.6 PROPERTIES OF METALS AND NON-METALS

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. 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. 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
