Question

Name one metal which is lustrous and a metal which is non lustrous

Answer 1

Lustrous metal is gold and non-lustrous metal is Sodium.

Explanation:

• The lustrous of the metal is obtained when there are enough free electrons. This results in the mirroring effect of the metal.

• The electromagnetic radiation is the sole reason behind the mirroring effect which happens in the metals.

• If a metal is supposed to be non-lustrous then its electromagnetic fields are not reacting with its surface in order for forming a particular reflecting surface.

• This is usually done by a non-metallic surface. Gold is one of the lustrous metals found which is primarily known due to its shine and colour.

• Sodium, on the other hand, is a silver-coloured soft metal which is non-lustrous in nature.
