Metallic lustre is due to
- A high density of metals
- B high polish on the surface of metals
- C reflection of light by mobile electrons
- D chemical inertness of metals
Answer & Solution
Correct Answer
(C) reflection of light by mobile electrons
Step-by-step Solution
Detailed explanation
The lustre of metals is due to the free electrons (or to be precise very loosly bound electrons). When light strikes the surface of the metal, the energy is absorbed by the electrons which absorb and then emit the absorbed energy or reflect it, this cause metals to have lustre.
