Chalcedony and corundum can both appear in white forms and have a Mohs hardness greater than most feldspars.
Calcite is a compound and therefore cannot be classified as a metal or nonmetal.
True. The luster of a mineral is described as either metallic or nonmetallic. Metallic luster reflects light like metal, while nonmetallic luster can vary from glassy to earthy in appearance.
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.
If a mineral has a shiny luster, is it matallicIf a mineral has no shiny luster, is it nonmetallic?
The nonmetallic physical characteristic of gypsum is its pearly or silky luster when it is broken into thin sheets or cleaved. This quality gives gypsum a unique appearance compared to metallic substances.
What is a whitish gray stones that leaves a colorless streak behind and is nonmitallic
Whitish-gray stones with a nonmetallic luster that leave a colorless streak are likely to be varieties of minerals such as quartz or feldspar. These minerals often exhibit a light color and can be found in many geological environments. Their nonmetallic luster and ability to leave a colorless streak are characteristic features used to identify them in mineralogy. Further examination, including hardness and crystal structure, would help in precise identification.
Calcite is a compound and therefore cannot be classified as a metal or nonmetal.
Yes, calcite is a nonmetallic mineral that is typically white or colorless. It has a vitreous to pearly luster and is commonly found in sedimentary rocks such as limestone and marble.
True. The luster of a mineral is described as either metallic or nonmetallic. Metallic luster reflects light like metal, while nonmetallic luster can vary from glassy to earthy in appearance.
I think its nonmetallic as it is glass
a ruby is nonmetallic
yes
There is not enough information to go on. Many minerals fit this description, especially since there are several types of 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.
The most common type of nonmetallic luster is called "vitreous" luster, which resembles the appearance of glass. Minerals with vitreous luster reflect light in a way that gives them a shiny and somewhat transparent look. Other types of nonmetallic luster include pearly, silky, and dull, but vitreous is the most frequently observed in various minerals.
The Luster of a mineral is it's appearance in the light. Also there are two types of Luster, metallic and nonmetallic.
