WEEK 4
\n<\/strong>CLASSIFICATION OF NON-LIVING THINGS INTO METALS AND NON-METALS
\n<\/strong>METALS
\n<\/strong>Metals are elements that readily form positive ions and have metallic bonds. Examples are copper, iron, copper, etc.
\nProperties of Metals<\/p>\n

    \n
  1. They are good conductors of heat and electricity\n<\/li>\n
  2. They are lustrous i.e. shiny and can be polished.\n<\/li>\n
  3. They are malleable, that is, they are capable of being beaten into thin sheets.\n<\/li>\n
  4. They are ductile, that is, they can be drawn into thin wire.\n<\/li>\n
  5. They are generally strong and hard with high tensile strength\n<\/li>\n
  6. They are sonorous, that is, they produce sound when struck.\n<\/li>\n
  7. They have high densities.\n<\/li>\n
  8. They have high melting and boiling points\n<\/li>\n<\/ol>\n

    NON-METALS
    \n<\/strong>These are elements that do not have the properties of metals. Examples are sulphur, nitrogen, oxygen, chlorine. Etc.<\/p>\n

    \u00a0Properties of Non-metals<\/p>\n

      \n
    1. \n
      They are poor conductors of heat and electricity\n<\/div>\n
        \n
      1. They are not lustrous\n<\/li>\n
      2. They are not malleable\n<\/li>\n
      3. They are not ductile\n<\/li>\n
      4. They are not sonorous\n<\/li>\n
      5. They have low melting and boiling point\n<\/li>\n
      6. They have low densities\n<\/li>\n<\/ol>\n<\/li>\n<\/ol>\n
