Unit 9.3 Materials

  • 9.3.1 know that metals, semimetals and non-metals have their unique properties (k) identify the different properties of metals: hardness, malleability, ductility, density and conductivity identify properties of Non-metals as: poor conductor, dull, brittle, low melting and boiling point. state that semi-metals have both metallic and non-metallic properties

    9.3.2 be able to show that the corrosion of metals is caused by environmental factors (s) demonstrate the corrosion process using iron nails in conditions e.g.

    i. iron nail in water

    ii. iron nail in oil

    iii. iron nail in air
