Q4 (Medium): Why are only a few metals suitable for making jewellery?

Answer:
We have studied that metals have different properties like malleability , ductility , and sonority . This is why only specific metals work for jewellery.

  • Gold and silver are most malleable
  • They are non-reactive with air and water
  • They have attractive lustre and do not rust
  • Other metals like iron get rusted easily
