Metallic luster is the shiny, reflective appearance of metals and some minerals. It is caused by the way light interacts with the electrons in the metal's atomic structure. When light hits a metal surface, the free electrons in the metal absorb and then re-emit the light, creating a smooth, mirror-like reflection. This unique interaction with light gives metals their characteristic luster, distinguishing them from non-metallic minerals which have a dull or glassy appearance.
