Graphene why is it so strong electrically conductive and
· Strength I know graphene contains covalent bonds which are strong and that it has a hexagonal lattice structure. Electrical conductance I know that each carbon atom has one free valence electron as it is covalently bonded to only three other carbon atoms and that graphene has no band gap and a high current density and a high intrinsic mobility.

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. This delocalised electron is no longer associated with one particular carbon atom and

Why Is Graphene Important ThoughtCo
· Graphene Can Be Used to Make Very Small Devices. Graphene conducts so much electricity in so small a space that it may be used to develop miniaturized super-fast computers and transistors. These devices should require a minuscule amount of power to support them. Graphene is flexible strong and transparent too.

· Graphite is made of planar sheets of carbon atoms in 6-atoms rings with conjugated double bonds. This also satisfies the 4n 2 π electrons criteria needed within the aromatic ring for graphite to be aromatic. This aromaticity is why graphite is not only stable to high temperatures but also a more thermodynamically favorable allotrope than

Why is graphite a good conductor of electricity
Graphite is a good conductor of electricity because in graphite carbon atom is combined with three nearest carbon atoms on the same surface and formed a hexagonal structure. While on end of them is free such surface from weak bonds hence it is used in dry cells and electric arc.

Why Are Graphite Electrodes Used in Electrolysis M
The main reason that graphite electrodes are used in electrolysis is that graphite is an excellent conductor. The structure of graphite is such that it has a large number of electrons floating freely between the different layers of atoms (graphite bonds are formed of only three out of the four electron shells of the carbon atom leaving the fourth electron to move freely).
