3 Explain why graphite is soft and slippery. Graphite is a semimetal and a stable form of carbon. PLAY. It is a free electron and these free electrons between the layers allows graphite to conduct electricity and heat. The layers in graphite can slide over each other because the forces between them are weak. Whereas, in graphite the carbon atoms only form 3 covalent bonds, creating hexagonally packed sheets of carbon. Both are made only of carbon atoms. Carbon alone forms the familiar substances graphite and diamond. Although graphite is a very stable allotrope of carbon but at a very high temperature it can be transformed into artificial diamond. Crude oil is made from hydrocarbons which can be processed to make a variety of fuels and other useful products. On the other hand, in diamond each carbon atom is the same distance to each of its neighboring carbon atoms. Both graphite and diamond are made only of carbon atoms. Graphite is a naturally occuring form of Carbon that is mined, ground and separated into desired sized particles. If both are made only of carbon what gives them different properties? These sheets are weakly bonded to each other, and can slip past each other easily. Diamond is the hardest substance known to man. 2.
In Graphite the carbon atoms are situated at corners of the regular hexagonal ring. Graphite is very soft and slippery. Hence, graphite is soft and slippery. Why is graphite a good conductor of electricity? If you use alum arms and an alum bulkhead, you will break the chassis. Hence, graphite is soft and slippery. Answer and Explanation: Carbon alone forms the familiar substances graphite and diamond. There are only weak intermolecular forces between the layers. Such layers of hexagonal rings are arranged parallel to one another and the fourth valency of carbon is unsatisfied. The forces of attraction between the layers of carbon are very weak. This makes the layers to slide over one another. 4.
Graphite is used to make the core or ‘lead’ in pencils because it is soft. See also carbon fibres and fullerenes. With those aluminum arms, you're sure to bust some bulkheads. In addition to being soft and slippery, graphite also has a much lower density than diamond. These internal forces make them weaker. The layers in graphite can slide over each other because the forces between them are weak. It is a native element miner. Since it has weak intermolecular forces, graphite would be slippery and soft enough to act as a lubricant.
