Answer 2

Answer:

A metal is a lattice of metal "ions" in a "sea" of delocalised electrons - mobile electrons. Photons of light do not penetrate very far into the surface of a metal and are typically reflected, or bounced off, the metallic surface, by the mobile electrons and what you get is metallic reflection, which is lustrous.
