Allotropes Of Carbon 0.0 / 5 ? ChemistryPolymersNanoscienceGCSEAll boards Created by: Simranjyot SinghCreated on: 13-02-18 18:35 What is an allotrope? Different structural form of the same element in the same physical state. 1 of 10 Why is diamond hard? Because the carbon atoms each form four covalent bonds. 2 of 10 Why does diamond have a high melting point? Because it has strong covalent bonds which require a lot of energy to break down 3 of 10 Why doesn't diamond conduct electricity? Because it has no free electrons or ions 4 of 10 What does graphite diagram look like? It is made of layers of carbon arranged in hexagons. Each of the carbon are connected to 3 other carbons 5 of 10 How many carbon electrons are used in the covalent bonding? 3 out of 4 electrons from the outer shell. 6 of 10 What is graphene?How are they connected? Graphene is one layer of graphite, these layers are connected with weak bonds 7 of 10 What is a fullerene? Molecules of carbon shaped as closed tubes or hollow balls. 8 of 10 What are nanotubes? They are carbon cylinders made from fullerenes. 9 of 10 Example of use of nanotube. Because it can be used to "cage" other molecules, it can be used to deliver drugs into your body. 10 of 10
