low price why graphite conducts electricity but sillicon

The trend from non-metal to metal in Group 4

2019-4-20 · Note: In graphite, each atom donates one electron to a delocalised system of electrons which takes in the whole of its layer. These electrons are free to move around, and so graphite conducts electricity - but this is a special case. If you are interested, the bonding in graphite is like a vastly extended version of the bonding in benzene.

Graphene - A simple introduction - Explain that Stuff

In fact, it behaves much more like a metal (though the way it conducts electricity is very different), and that''s led some scientists to describe it as a semimetal or a semiconductor (a material mid-way between a conductor and an insulator, such as silicon and germanium). Even so, it''s as well to remeer that graphene is extraordinary—and

Metalloid - Wikipedia

2019-4-17 · A metalloid is a type of chemical element which has properties in between, or that are a mixture of, those of metals and nonmetals. There is neither a standard definition of a metalloid nor complete agreement on the elements appropriately classified as such. Despite the lack of specificity, the term remains in use in the literature of

Electrical resistivity and conductivity - Wikipedia

2019-4-9 · Electrical resistivity (also called specific electrical resistance or volume resistivity) and its converse, electrical conductivity, is a fundamental property of a material that quantifies how strongly it resists or conducts the flow of electric current. A low resistivity indies a material that readily allows the flow of electric current.

Does carbon conduct electricity? If it does, why is it

Carbon itself does not conduct electricity, but its allotrope graphite does. This is because graphite has a “free” electron in its outer shell that allows it to conduct some electricity. Metals have many free electrons and therefore are much better conductors of electricity.
