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.

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
What are the three forms of carbon?
The three allotropes (forms) are ;- Graphite Diamond Buckminster Fullerene (Footballene). Do NOT confuse with Isotopes. Carbon also exhibits three isotopes viz'. Carbon -12 (The most common isotpe) Carbon - 13 (used in nmr) Carbon - 14 (used in carbon dating). An allotrope is an element that exhibits differen physical characteristics. An isotope is an element that has a different number of neutrons in the nucleus.
Found in these forms charcoal graphite diamond?
If YOU write in this area, your question goes to the "already answered" bucket- Besides its use as jewelry, Diamond is used where anything incredibly hard is needed. Diamond (dust) is used to make saw blades and drill bits that can cut through just about anything. Graphite, while also composed of carbon, has an entirely different crystal structure, and different uses. Graphite is used as an electrical contactor (a brush) in electrical motors. It makes a great dry lubricant for things like locks, and when mixed with clay, forms the "lead" for ordinary pencils.
What is allotropywhat are allotropic forms of carbon?
Allotropy is when an element has different forms. Some allotropes of carbon include graphite, diamond, and Buckminsterfullerenes, as well as others.https://en.wikipedia.org/wiki/Allotropes_of_carbon
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?
Allotropic carbon: Organic carbon graphite diamond All are pure carbon, just of different structural forms. In the case of carbon, lattice structural differences in the graphite and diamond forms.
What forms of carbon is used for radiocarbon dating?
The radioactive isotope 14C.
