2.2.8 Properties of Metals and Alloys

Cards (2)

  • Describe properties of metals.
    High melting/boiling points (strong forces of attraction). Good conductors of heat and electricity (delocalised electrons). Malleable, soft (layers of atoms can slide over each other whilst maintaining the attraction forces).
  • What are alloys? Why are they harder than pure metals?
    Alloys: Mixtures of metal with other elements, usually metals. Different sizes of atoms distorts the layers, so they can slide over each other, therefore alloys are harder than pure metals.
