Question

Which reason best explains why metals are shiny? because their valence electrons reflect light because their valence electrons absorb light because their valence electrons oscillate between bands because their valence electrons move to higher energy levels

Answer 1

valency of electrons oscillate between bands...

Answer 2

Answer: Option (a) is the correct answer.

Explanation:

Metals have excess of electrons which are loosely attached to each other. Thus, they move freely from one point to another within the metal or on its surface.

While these outermost electrons were moving, the light falling on them gets reflected back. This reflection is specular in nature and not diffused that is why light gets reflected.

Thus, we can conclude that metals are shiny because their valence electrons reflect light.
