What are five metallic minerals?
nickel (pentlandite), copper (chalcopyrite), zinc (sphalerite), lead (galena) aluminum (bauxite)
The streak of a mineral is much more accurate in identifying a mineral than color. The streak of a mineral can distinguish minerals with metallic and non-metallic luster. For example, metallic minerals generally have a dark streak whereas non-metallic luster minerals often have a light colored streak.
