What is the oxidation number of carbon-atom in diamond?
zero for carbon in diamond
What is pure carbon in the form of a diamond made of?
Diamond is an allotrope of carbon: pure carbon is made of pure carbon, by definition.
Does diamond have a metallic bond?
No, diamond, an allotrope of carbon, does not have a metallic bond. Carbon, which is the element from which diamond is formed, is a nonmetal.
Can you remove carbon from a diamond?
No. A diamond is all carbon, except for trace minerals what may give the diamond colour.
How you abbreviate diamond?
If you think to diamond as a carbon allotrope, the chemical symbol of carbon is C.
Is the diamond the hardest material?
Diamond has an extremely strong covalent bonding between carbon atoms; today diamond is not considered the hardest material, Today the hardest material is Aggregated diamond nanorods.
What is the hardest substance on the earth?
Aggregated Diamond NanorodsADNRs, are an allotrope of carbon believed to be the hardest and least compressible known material, as measured by its isothermal bulk modulus; aggregated diamond nanorods have a modulus of 491 gigapascals (GPa), while a conventional diamond has a modulus of 442 GPa. ADNRs are also 0.3% denser than regular diamond.The ADNR material is also harder than type IIa diamonds and ultrahard fullerite.A process to produce the substance was discovered by physicists in Germany, led by Natalia Dubrovinskaia, at the University of Bayreuth in 2005.ADNRs are made by compressing allotropic carbon fullerene molecules (generally 60 carbon atoms per molecule) to a pressure of 20 GPa, while at the same time heating to 2500 Kelvin, using a unique 5000 metric tonne multi anvil press. The resulting substance is a series of interconnected diamond nanorods, with diameters of between 5 and 20 nanometres and lengths of around 1 micrometre each.They have used diamonds to cut steel.Its diamond
What is the the hardest substance known?
The hardest substance on earth are things called Carbon Nanotubes. It's quite some times harder than diamond earning it well above a 10 on the Mohs Scale. This object is synthetic, being made by man. However, there is another substance called Rhenium diboride that is also harder than diamond; another from of a nanotube.
What is the hardest manufactured material?
steel boron carbide is stronger than steel I do believe To date, probably carbon nanorods. Carbon is strongest, but in might be nanorods, nanotubes, or fiber. I'm not sure. A particular arrangement of carbon called Lonsdaleite (both naturally occurring in trace amounts and manufactured) is the hardest known material to date. pure samples have been recorded to be 58% harder than diamond, however when found naturally, impurities cause the Mohs Hardness to be only 7-8 (diamond is 10 on this scale).
What is the hardest and lightest mental?
The hardest known metal alloy, and the hardest known metal in general, is a type of carbon steel, Alloy 1090. With a tensile strength of .84 GPa (122,000 psi) and a yield strength of .64 GPa (67,000 psi), carbon steel is surpassed in hardness only by very hard nonmetals, such as ruby, diamond, or aggregated diamond nanorods. The best high-carbon steels rate an 8 on the Mohs scale of hardness, relative to ruby at 9 and diamond at 10. The hardest metals are still somewhat soft in comparison to the strongest nonmetals, based on the strongest bonds in chemistry, the sp2 bond between carbon atoms. High-strength carbon steel goes through a process of tempering and annealing to make it harder. After this process is complete such steel is called strengthened steel, the hardest metal available. Carbon contents as great as 2% may be present in the hardest metal..
Diamond is which form of carbon?
Diamond is the diamond form of carbon
What element is in a diamond?
Diamond is produced from the element carbon.
What is pure carbon?
One pure form of carbon is diamond.
What gemstone is made up of only carbon atoms?
Diamond is composed of the element carbon.
Are diamonds made of carbon dioxide?
Carbon under pressure for millions of years will make diamonds.
What is the oxidation number of carbon-atom in diamond?
zero for carbon in diamond
Is diamond an elemental carbon?
Diamond is an allotrope of carbon.It is not an elemental carbon.
