Understand that metallic luster refers to the shiny, reflective surface characteristic of certain elements.
Recall that metals are known for their ability to reflect light, which gives them a shiny, metallic appearance.
Recognize that metalloids have properties intermediate between metals and nonmetals, so their luster is not typically metallic.
Note that nonmetals generally do not exhibit metallic luster; they tend to be dull or transparent.
Remember that noble gases are gases at room temperature and do not have a solid surface to exhibit luster.
