No they do not.
That would completely depend upon the form of Carbon. Carbon can be found as coal, graphite, or diamond to name a few.
No, diamond and graphite do not form the same product when burnt. Diamond will convert into carbon dioxide gas, while graphite will also convert into carbon dioxide gas.
Most anything can 'cut graphite' including your fingernail.
Two types of carbon are graphite and diamond. Graphite is a soft, dark gray form of carbon, while diamond is a colorless, transparent form of carbon renowned for its hardness and brilliance.
Diamond is a gem because of its rarity, hardness, brilliance, and value. Graphite, on the other hand, is not considered a gem because it lacks the clarity, brilliance, and color that are typically associated with gemstones. Additionally, graphite is not as rare or valuable as diamonds.
No
Diamond is the only mineral that has the same hardness as corundum, which is the second hardest natural mineral on the Mohs scale after diamond. Both corundum and diamond have a hardness of 9 on the Mohs scale.
The crystalline structure of graphite and diamond are very different.
Graphite is less dense than diamond, due to the differences in crystal structure.
pure carbon. its the same as diamond
They are not made the same- but they come from the same element- carbon. However, carbon can take different crystal shapes. One of those is graphite, a very different one is diamond.
Carbon in its pure form lacks the typical hardness of a metal, so it can be scratched or dented with sufficient force or pressure. However, the hardness can vary depending on the form of carbon, such as graphite or diamond, with diamond being extremely hard and difficult to scratch or dent.
