Do minerals that contain metal often have a shiny luster?
Yes. They do.******Contrablue Adds:Unfortunately, this is often incorrect. Many metals are found in chemically "bound" form in their ores -- that is, they are in the form of salts or other compounds rather than the shiny metal. For example, copper is often found in the form of copper carbonate, which is a beautiful green mineral (pure specimens are called "malachite"). But malachite doesn't have a shiny luster because the copper is chemically bonded to oxygen and carbon!The only metals likely to be found "native" or in the uncombined, shiny state, are noble metals such as gold or platinum.The answer is True
What is metallic luster?
Metallic luster is the shiny, reflective appearance exhibited by metals and some minerals. It is typically characterized by a high degree of reflectivity and brightness, similar to the sheen of polished metal surfaces. Minerals with metallic luster often have a metallic appearance due to the presence of metallic elements in their chemical composition.
What is adamantine luster?
Adamantine luster is a term used to describe a shiny, brilliant, and reflective luster on minerals or gemstones. It is often associated with diamond-like or metallic sheen, indicating a high level of light reflection and clarity in the material.
What minerals has non-metallic luster and can have the shape of little cubes?
Minerals such as galena, pyrite, and halite can have non-metallic luster and exhibit crystal faces that resemble small cubes. These minerals can often form in cubic or octahedral crystal shapes due to their internal atomic arrangement.
What is nonmetallic luster?
Nonmetallic luster refers to a dull or earthy appearance of a mineral or material that lacks the shiny or reflective properties of metallic luster. Nonmetallic luster can be described as having a matte, powdery, or waxy finish, often seen in minerals like talc or graphite.
Do minerals containing a metals often had a shiny luster?
yes
Does minerals containing metals often have a shiny luster?
Yes they doAnswer:Some do and some don't - iron pyrites, gold, silver, lead ores - may have a luster. Others like bauxite (aluminum ore), pitchblende (uranium), iron ore are not lusterous.
What does luster mean in chemistry?
In chemistry, luster refers to the way a substance reflects light. Substances with high luster appear shiny and reflective, while substances with low luster appear dull. Luster is often a characteristic used to describe the physical appearance of metals and minerals.

A type of luster which resembles that of broken glass?
This type of luster is known as subadamantine. It is characterized by a shiny, reflective appearance similar to broken glass, often seen in minerals like diamond, zircon, and sphalerite.
Which type of luster gives the mineral appearance of metal?
The type of luster that gives a mineral the appearance of metal is known as "metallic luster." Minerals with metallic luster reflect light in a way that resembles polished metal, often appearing shiny or reflective. This characteristic is typically seen in minerals like pyrite or galena. In contrast, non-metallic luster includes a range of appearances such as glassy, pearly, or dull.

What is nonmetallic luster?
Nonmetallic luster refers to a dull or earthy appearance of a mineral or material that lacks the shiny or reflective properties of metallic luster. Nonmetallic luster can be described as having a matte, powdery, or waxy finish, often seen in minerals like talc or graphite.
