Why does metal and graphite conduct electricity in …
2009/4/23· For a substance to conduct electricity, it must contain freely moving charged particles - either electrons or ions - that can carry the charge of the electric current through the substance. In both graphite and metal there are ''delocalised'' electrons that are not firmly bound to any particular atom and are free to move about within the substance, carrying the current
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

Why do metals conduct electricity? | Socratic
2018/5/25· Metals conduct electricity well because they have a very low resistance that decreases the difficulty that there is for the current to pass through them (around 0.0001 ohms). They also have a lot of free electrons in them which provided the electricity to move more efficiently, consequently, copper (a metal #Cu# ) is used to make wires.

2020/3/21· So why is graphite different to diamond? The atoms inside the two materials are arranged in different ways, and this is what gives the two allotropes their completely different properties: graphite is black, dull, and relatively soft (soft and hard pencils mix graphite with other materials to make darker or fainter lines); diamond is transparent and the hardest natural material so far discovered.
