Why is diamond denser than graphite? - Quora
WebSep 26, 2024 · These carbon atoms in graphite have the tendency to bond with weaker intermolecular forces such that these layers slide over each other. This is the reason why diamond is harder than graphite. ... As an example, you can scratch steel with a diamond, but you can easily shatter a diamond with a hammer. The diamond is hard, the … WebAnswer (1 of 2): Both diamond and graphite are allotropes of Carbon. But there is one major distinction that makes them completely different from each other. * Crystal system. Graphite is hexagonal/rhombohedral (alpha/beta when crystalline) while diamond is cubic (FCC). This basically dictates ... granite oregon weather 10 day
Diamond and graphite - Giant covalent molecules - BBC …
WebIn graphite, each carbon atom is only covalently bonded to three other carbon atoms, rather than to four as in diamond. Graphite contains layers of carbon atoms. The layers slide over each other easily because there are only weak forces such as Van der Waals force between them, which makes graphite slippery. Hence, the correct answer is option C. WebThe bonds between each layer are fairly weak and allow the layers to be easily separated or even to slide over each other. It is the most common naturally occurring form of carbon and if it is subjected to very high pressure and temperature, it will become diamond, the other naturally occurring form of carbon. WebDiamond is an allotrope of carbon where each carbon atom is covalently bonded to four other carbon atoms. ... This means applying some pressure to graphite makes the layers slide over each other quite easily. This is how pencils work: graphite layers slide off of the pencil and onto the paper we write on when we press the pencil down! ... chinn\u0027s 34th street fishery closing
