Substance A is malleable, ductile, conducts electricity well, and has a melting point of 1135 °C. Substance B is brittle, does not conduct electricity as a solid but does when molten, and has a melting point of 2072 °C. Substance C is very hard, does not conduct electricity…

Allotropes of carbon - Wikipedia

Likewise, under standard conditions, graphite is the most stable form of carbon. Therefore, it is used in thermochemistry as the standard state for defining the heat of formation of carbon compounds. Graphite conducts electricity, due to delocalization of the pi bond electrons above and below the planes of the carbon atoms. These electrons are free to move, so are able to conduct electricity.

Why is graphite a good conductor of electricity but …

1 Answer. (a) In a graphite molecule, one valence electron of each carbon atom remains free, Thus making graphite a good conductor of electricity. Whereas in diamond, they have no free mobile electron. Thats why diamond are bad conductor electricity. (b) A diamond is a giant molecule.

Chapter overview. 2 weeks. This chapter builds on the chapters about the properties of materials in Gr. 5 and 6 Matter and Materials. Some of the properties learners encountered in the earlier grades are revisited, but now we start placing greater emphasis on how properties that may be desirable in a consumer product, may become undesirable properties when that product turns to waste.

Allotropes of carbon - Wikipedia

Graphite, named by Abraham Gottlob Werner in 1789, from the Greek γράφειν (graphein, "to draw/write", for its use in pencils) is one of the most common allotropes of carbon.Unlike diamond, graphite is an electrical conductor. Thus, it can be used in, for instance, electrical arc lamp electrodes. Likewise, under standard conditions, graphite is the most stable form of carbon.

Why can graphite conduct electricity but not diamond

Graphite on the other hand, although also only made up of carbon atoms, is the only non-metal that can conduct electricity. This is because only 3 of the available valence electrons form covalent bonds leaving 1 spare electron, which then becomes delocalised.

Graphene was first isolated in 2004 by using tape to peel off thinner and thinner layers from graphite. It is essentially a single sheet (one atom thick) of graphite. Graphene, illustrated in , is not only strong and lightweight, but it is also an excellent conductor of electricity and heat. These properties may prove very useful in a wide range of appliions, such as vastly improved computer chips and circuits, better …

Dry Cell Electricity and Circuits-Science-Class-6

Do you know why Graphite conducts Electricity? - …

It it because of electron delocalisation in the layers. Graphite has a structure consisting of layers of hexagons of carbon. Just like benzene rings, the rings in the layers have delocalized pi electrons, and because all the rings are coupled, these pi electrons can move all along the layers and conduct electricity.
