What 2 forms of carbon are found in nature?
Diamond and Graphite are the two pure forms of carbon
Which has the less density graphite or diamond?
Graphite is less dense than diamond, due to the differences in crystal structure.
What can graphite be scratched by?
Graphite can be scratched by materials that are harder than it, such as diamond and tungsten.
Graphite is an allotrope of what element?
Diamond, graphite and carbon black are the most common allotropes of CARBON
An element that has two allotropic forms called diamond and graphite?
Carbon has two allotropic forms called diamond and graphite. Diamond is a hard, transparent crystal structure, while graphite is a soft, dark crystal structure known for its lubricating properties.
Is carbon opaque?
It depends on what form its in. Most forms of carbon are opaque. Diamond, however, is transparent.
Is a basketball transparent or translucent or opaque?
its opaque, its not transperent because you cant see the inside of it. transculent isn't either because it creates shadow.
What are the key differences between the properties of diamond and graphite?
Diamond and graphite are both forms of carbon, but they have different properties. Diamond is a hard, transparent crystal with a high melting point, while graphite is a soft, opaque material with a lower melting point. Diamond has a three-dimensional structure, making it hard and durable, while graphite has a layered structure, allowing it to be used as a lubricant.
What are the key differences between graphite and diamond in terms of their physical properties and uses?
Graphite and diamond are both forms of carbon, but they have different physical properties and uses. Graphite is soft, opaque, and a good conductor of electricity, while diamond is hard, transparent, and a poor conductor of electricity. Graphite is commonly used in pencils, lubricants, and electrodes, while diamond is used in jewelry, cutting tools, and industrial applications requiring hardness and durability.
The chemical composition of graphite and diamond is?
Graphite and Diamonds are both allotropes of Carbon.
Do both diamond and graphite have a crystal structure?
Yes. Diamond is isometric, graphite is hexagonal.
Which can be used as a lubricant - graphite or diamond?
graphite
What is the physical appearance of carbon?
Carbon exists in various forms, including black powder (graphite), shiny crystals (diamond), and buckyballs (fullerenes). The physical appearance of carbon depends on its form, such as being opaque and flaky in graphite, transparent and refractive in diamond, or resembling a hollow sphere in fullerenes.
Is graphite transparent or opaque?
Graphite is opaque, meaning it does not allow light to pass through it. This is because graphite is made up of layers of carbon atoms arranged in a way that absorbs and scatters light rather than allowing it to pass through.
How do polymorphs of carbon differ in terms of their physical and chemical properties?
Polymorphs of carbon, such as diamond and graphite, differ in their physical and chemical properties due to their different atomic arrangements. Diamond is hard, transparent, and has a high melting point, while graphite is soft, opaque, and has a lower melting point. Additionally, diamond is a poor conductor of electricity, while graphite is a good conductor. These differences arise from the unique bonding structures of each polymorph.
What does graphite turn into when put under pressure?
Graphite turns into diamonds when put under extreme pressure and heat. Diamond is a denser and harder form of carbon compared to graphite.
Why diamond is brilliant versus graphite is opaque?
Coal (graphite) is black and diamonds are clear because of the way carbon atoms are connected. In diamond each carbon atom is connected to the others forming points of a pyramid. In graphite (coal) the atoms are connected forming flat planes. These planes can absorb light of all wavelengths and hence are black. The pyramids in diamond, on the other hand cannot absorb any visible light and reflect all of it and thus are transparent.
