What else can I help you with?
Are Graphite galena and pyrite are all metallic minerals?
Graphite is a form of carbon and is considered a non-metallic mineral due to its applications and properties, despite having metallic luster. Galena, on the other hand, is a lead sulfide and is classified as a metallic mineral because it contains a metal (lead) and exhibits metallic characteristics. Pyrite, often referred to as "fool's gold," is also a metallic mineral, primarily composed of iron and sulfur. Thus, while galena and pyrite are metallic minerals, graphite is not.
What color streak does graphite have?
The same color as the writing from a pencil, very dark grey or black. Pencils used to be made of graphite
Which mineral has a metallic luster is gray and can be scratched with a fingernail?
The mineral you are describing is likely graphite. Graphite has a metallic luster and appears gray in color. It is soft enough to be scratched with a fingernail, which distinguishes it from many other minerals. This characteristic makes graphite an important material in applications such as pencils and lubricants.
Which is non metallic element which is a conductor of electricity?
Graphite is a non-metallic element that can conduct electricity. It has a unique structure that allows electrons to move freely within its layers, making it a good conductor of electricity.
Is graphite a mixture or metallic element?
Graphite is a pure substance and a crystalline form of carbon. It is not a mixture since it is composed of only one type of atom, carbon. Additionally, graphite is not a metallic element, it is a non-metal.
Is graphite metallic or non metallic?
Graphite is not metallic it just "shines" when the light shines on it
What is the luster of a graphite?
Graphite is black and posseses dull appearance
Is a non metallic conductor?
Water Graphite is an excellent electrical conductor.
What is non metallic conductors?
Graphite
Which is the softest metallic mineral on earth?
Graphite
In which part of the pencil are metallic bonds found?
Metallic bonds are typically found in the graphite core of a pencil, which is what allows the graphite to conduct electricity. Graphite is a form of carbon that consists of layers of atoms held together by metallic bonds.
Which non metallic solid is not an electrical insulator?
graphite
Is wax a giant covalent structure?
No, wax is not a giant covalent structure. Wax is composed of long-chain hydrocarbons and does not have a complex molecular structure like giant covalent substances such as diamond or graphite.
Does talc or graphite have more metallic luster advances?
Graphite has more metallic luster properties compared to talc. Graphite has a greasy feel, excellent conductivity, and metallic luster properties due to its layered atomic structure, whereas talc has a pearly luster and is not a good conductor of electricity.
Why graphite a nonmetal?
Graphite is a form of the element carbon, which is a nonmetal. While it has a metallic luster and conducts electricity, graphite is brittle. Unlike metals, which are held together by metallic bonds, graphite is a covalent network solid. Other forms of carbon behave more clearly as nonmetals.
Is a sharpened pencil lead metallic or non-metallic?
A sharpened pencil lead is non-metallic. It is typically made of graphite, which is a non-metallic element.
Is carbon metallic?
No, carbon is not a metal. It is a non-metallic element that can exist as a solid (such as graphite or diamond), liquid (such as in molten form), or a gas (such as in carbon dioxide).
