Why graphite conducts electricity? Sample question: The structure of graphite has one feature in common with that of the metals. This feature allows graphite to conduct electricity. Suggest what is this feature is and why it allows graphite to conduct electricity.
Give reason :Graphite is used as lubricant. toppr
Graphite is used as a lubricant due to its slippery nature.The layers in graphite can slide over each other because the forces between them are weakDue to its loosely intact carbon atoms or free electrons, they can move around easily from one place to another, making graphite a good conductor of electricity.

what is the only non metallic element that conducts …
23/9/2006· Carbon is the only non-metal that conducts electricity but only when it is as the allotrope graphite. Carbon can also arrange itself to diamond, which doesn''t conduct electricity. An allotrope means a different way that an element bonds, when carbon bonds to make graphite it will conduct electricity because there are some free electrons.
Is graphite a good conductor of electricity? | Yahoo …
10/11/2008· For example, silicon is an insulator in the dark, but conducts electricity when bathed in UV light. Note that semiconductors are generally poorer conductors than conductors. 0 0 0 Log in to reply to the answers Post kumorifox Lv 7 1 decade ago Yes, very good.
Why is graphite a good conductor of electricity? | …
18/12/2010· Graphite does not behave by the definition of a semi conductor because it has good forward and back direction of electricity while semi-conductors dont. In case of graphite the carbon atoms naturally coine covalently with three other carbon atoms so every coined carbon has one unshared or free electron.
Which is the most stable allotrope of carbon? - ProProfs …
It basically conducts electricity along the carbon atoms plane but refuses to conduct at a right angle degree to the plane. In thermochemistry, it is used as the standard or basic state for determining heat formation in compounds of carbon. Graphite does not burn
