Phosphorus does not have a metallic luster in its most common forms. Here's why:

* White phosphorus is a waxy, translucent solid with a yellowish color.

* Red phosphorus is a dark red, powdery solid.

* Black phosphorus is a black, flaky solid with a metallic sheen.

Therefore, only black phosphorus exhibits a metallic luster. However, it is not as common as white or red phosphorus.

Metallic luster is a characteristic of metals. It's caused by the way light interacts with the free electrons in the metal's structure. While phosphorus is a nonmetal, black phosphorus has a structure that allows for some metallic properties.
