4. Metals are Lustrous (or Shiny), and can be Polished.
For example, gold, silver and copper are shiny metals and they can be polished. The property of a metal of having a shining surface is called metallic lustre (chamak). The shiny appearance of metals makes them useful in making jeweller/ and decoration pieces. For example, gold and silver are used for making jewellery because they are bright and shiny. The shiny surface of metals makes them good reflectors of light. Silver metal is an excellent reflector of light.
