Carbon manifests itself in a number of allotropes. * Amorphous: black particles like soot from a flame. * Graphite: black hexagonal crystals that can slide over each other. Used in dry lubricants and pencils (the "lead"), it is one of the softest substances * Diamond: clear tetrahedral crystals, rated a 10 on the Mohs hardness scale, and is the hardest known natural substance. It is used as jewellery and as an additive to or the basis for many industrial cutting, grinding and other similarly used tools. * Carbon 60 is a recently discovered allotrope, shaped like a Basketball, called fullerenes after Buckminster Fuller, an architect of geodesic dome structures. * Nanotubes are small tubes constructed of flat sheets made from graphite. There are many potential uses for them, which are being tested all over the world.
The different forms of carbon include diamond, graphite, fullerenes, and carbon nanotubes. Diamonds are used in jewelry and cutting tools, graphite is used in pencils and as a lubricant, fullerenes have potential applications in medicine and materials science, and carbon nanotubes are used in electronics and materials engineering.

What are different non-crystalline forms of carbon?
Different non-crystalline forms of carbon include amorphous carbon, activated carbon, carbon black, and carbon nanotubes. These forms have irregular atomic structures and lack long-range order typical of crystalline forms like diamond or graphite.
What are carbon molecules used for?
carbon has various allotropic forms, i. e. carbon molecules don't exist independently. The forms, majorly, Graphite (Used for lubrication and many other purposes), Diamond (Jewellery and precision instruments) and fullerenes.
What are elements called that exist in different forms?
If they are in different physical form they are ALLOTROPES. If they are in different atomic form they are ISOTOPES. e.g. Allotropes [ Graphite, diamond and buckyballs* buckminster Fullerene) are allotropes of carbon. They appear different because the arrangment of the atomis is different. Isotopes Carbon 12 , Carbon-13, Carbon-14 are isotopes of carbon , because they have a different number of neutrons in the nucleus.
Define allotrophy and names the allotropes of carbon?
Allotropy is the phenomenon where an element can exist in different physical forms or structures. The allotropes of carbon include diamond, graphite, graphene, fullerenes (such as buckyballs and carbon nanotubes), and amorphous carbon. Each allotrope has a unique arrangement of carbon atoms, resulting in different properties.
What are different atomic forms of an element?
An element can exist in different atomic forms known as isotopes, which have the same number of protons but different numbers of neutrons. For example, carbon has isotopes like carbon-12 and carbon-14. Additionally, an element can form ions by gaining or losing electrons, resulting in charged particles with different electron configurations.
What are different non-crystalline forms of carbon?
Different non-crystalline forms of carbon include amorphous carbon, activated carbon, carbon black, and carbon nanotubes. These forms have irregular atomic structures and lack long-range order typical of crystalline forms like diamond or graphite.
Are diamond and graphite different structural forms of carbon?
yes
Found in these forms charcoal graphite diamond?
These are three allotropes of carbon, each with distinct properties. Charcoal is a carbon-rich material used for drawing and fuel. Graphite is a soft, slippery form used in pencils and lubricants. Diamond is a hard, transparent form prized for its brilliance and used in jewelry and industrial applications.
What is allotropywhat are allotropic forms of carbon?
Allotropy is the property of some elements to exist in multiple different forms with different physical and chemical properties. The allotropic forms of carbon include diamond, graphite, graphene, and fullerenes (such as buckyballs and nanotubes). Each form has a unique arrangement of carbon atoms, resulting in distinct properties.
Are quartz and diamond different forms of pure carbon?
No. Diamonds are pure carbon but quartz is the compound silicon dioxide.
Why can pure element of carbon exist in different forms?
The different forms of pure carbon, such as diamond and graphite, are due to variations in the arrangement of carbon atoms. In diamond, each carbon atom is bonded in a tetrahedral structure, making it very hard. In graphite, carbon atoms are arranged in layers that can slide over one another, giving it properties like lubrication and conductivity.
What are carbon molecules used for?
carbon has various allotropic forms, i. e. carbon molecules don't exist independently. The forms, majorly, Graphite (Used for lubrication and many other purposes), Diamond (Jewellery and precision instruments) and fullerenes.
Is graphite and diamond an element?
No, graphite and diamond are not elements. They are both forms of the element carbon. Carbon is the element, while graphite and diamond are allotropes, which are different forms of the same element with different physical and chemical properties.
What are elements called that exist in different forms?
If they are in different physical form they are ALLOTROPES. If they are in different atomic form they are ISOTOPES. e.g. Allotropes [ Graphite, diamond and buckyballs* buckminster Fullerene) are allotropes of carbon. They appear different because the arrangment of the atomis is different. Isotopes Carbon 12 , Carbon-13, Carbon-14 are isotopes of carbon , because they have a different number of neutrons in the nucleus.
Why are allotropes not a different element?
Allotropes are different forms of the same element, with different molecular structures. They are composed of the same type and number of atoms but arranged in distinct ways, resulting in different physical and chemical properties. This variation in structure leads to diverse properties and behaviors among allotropes of the same element.
What forms of carbon is used for radiocarbon dating?
The radioactive isotope 14C.
What are different forms of a element?
An element can exist in different forms called allotropes, which have the same chemical composition but different structures. For example, carbon can exist as graphite, diamond, or fullerene. These different forms of elements can have distinct physical and chemical properties.
