Because they form . Graphite and diamond have very different structures. Exam. In diamond one carbon atom isbonded with four other carbon atoms with strong covalent bond so it is hard while in case of graphite each carbon forms two strong bonds with other two carbon atoms and one weak bond is formed with third carbon atom and forms hexagonal rings which slide over each other so it Image adapted from source1, source2. Graphite and diamond look different because the carbon atoms bond to one another in different ways in the two minerals. The same element can have multiple such floor plans leading to crystals w/different properties - we call these different arrangements ALLOTROPES & carbon (C) has multiple. It's simple chemistry. This makes diamond extremely hard. Diamond has a three-dimensional network of covalent bonds and is hard. Electrical Industry. Indicate the properties of each. Graphite and diamond are two of the most interesting minerals. Explanation: Diamonds and graphite are both allotropes of Carbon. Diamond and Graphite, both are known as the allotropes of carbon. Diamond has a face-centered cubic crystal structure while graphite has a planar structure. The phenomenon of the existence of a chemical element in two or more forms differ in physical properties but of the same chemical nature is known as Allotropy. Nonetheless graphite is as interesting a material as . Diamond is hard because the carbon atoms in diamond are in a stronger pattern than the carbon atoms in graphite, but it is soft and slippery because of the weak vanderwall force that holds the layers together. Carbon has two major allotropes diamond and graphite and the third one is Buckminsterfullerene. Both graphite and diamond have very similar energies of formation at normal conditions, though graphite is marginally more stable (the particular arrangement of bonds has a slightly lower energy than the arrangement in diamond under normal conditions). On the other hand, you can see from the illustration below that Graphite is made up of sheets of carbon atoms that have . So, right from the get-go, we see a distinct separation there. The other two forms that we won't mention any further are carbon nanotubes and fullerenes. Graphite is mostly just very thin sheets, and diamond is a very cubic structure arrangement of atoms.

Essentially, both diamonds and graphite are one of the four forms of pure crystalline carbon. 2) It is made up of tetrahedral units. In the case of Diamonds, you can see from the illustration below that its structure is an interwoven mesh and this is why it is such a hard, strong mineral. As a result, graphite is soft. Diamonds don't conduct electricity because it has no. Allotropes are compounds of the same composition, but exists in two or more different forms due to the different bonding. A. Main Differences Between Diamond and Graphite Diamond is naturally occurring hardest element, whereas, on the other hand, graphite is also a naturally occurring mineral, but becomes economical graphite only through manufacture. Although each allotrope is made of carbon, the different arrangement of the carbon atoms results in very different physical properties (for . Diamond. Graphite is comparatively softer. A chemical . On the other hand, graphite is an allotrope of carbon; this means it is a substance made solely of pure carbon. But in fact they are very different. The key difference between graphite and graphene is that graphite is an allotrope of carbon having a high number of carbon sheets whereas graphene is a single carbon sheet of graphite. Most graphite found near Earth's surface was formed within the crust at lower temperatures and pressures. B. Diamonds have a tetrahedral-like composition while graphite has a hexagonal-like arrangement layered in sheets. 4.Electrons in the diamond can't roam freely making it very hard. free electrons or ions. They both have giant structures of carbon atoms, joined together by covalent bonds.
