Graphite, an allotrope of carbon, is classified as a semimetal, that is, a material that shares some of the properties of metals. Many other non-metallic materials conduct electricity; including salts, plasma and some polymers.

Why is tin a good conductor or heat and electricity?
All metals Conduct:Tin, steel, iron, copper, aluminum, zinc and all other metals conduct electricity very well compared to most other compounds. (These pure metals conduct, but when they are used to form compounds, the result may of may not conduct electricity.)Why metals conduct:With the discoveries in solid state physics of the 20th century we learned that metals are collections of atoms which have somewhat unusually properties of the electrons. In metals the outermost electron (sometimes two) is not specifically associated with that one atom but is free to associate with atoms far and wide. We say these are delocalized electrons. Since the electrons are not attached to specific atoms, it takes very little energy to move them. As a result, any small voltage causes electron flow in a metal.This movement or flow of electrons is called electricity so this is why metals conduct electricity.Aside: Metals are not the only materials that conduct electricity, they just do it especially well.
Why does aluminum oxide not conduct electricity as a solid?
Sodium Iodide is held together by covelent bonds, therefore no "free" electrons exist which is what makes metals conductive. - Bird.
Does carbon graphite solid conduct electricity?
Yes, to some degree, in the plane of the rings. It doesn't conduct well perpendicular to them.
Is a soda can a good conductor of electricity?
Coke is the solid carbonaceous material derived from destructive distillation of low-ash, low-sulfur bituminous coal. Cokes from coal are grey, hard, porous, and not considered good at conducting electricity.
Is liquid metal a conductor or an insulator?
Most metals are conductors in solid and liquid state. (but there are a few exceptions to the rule)
Which substance conducts electricity in both molten and solid states?
Ag (silver) because it is a metal and metals conduct electricity no matter in solid or liquid phase.
Which metals conduct electricity when in solid?
Zinc and other metals
Is Mercury electric?
Liquid mercury can conduct electricity, it's what makes mercury thermostats work. As for solid mercury, it conducts electricity in solid phase as all metals do.
Do covalent compounds conduct electricity?
No. Covalent substances do not conduct electricity in solid or liquid state.
Do materials with ionic bonds conduct electricity in a solid and liquid state?
Materials with ionic bonds normally conduct electricity only in a liquid state. However metals, which have what are sometimes called "delocalized" ionic bonds, also conduct electricity in the solid state. It is now customary to consider metallic bonds a separate class from both ionic and covalent bonds.
What type of substance can conduct electricity in the liquid but not solid phase?
Most ionic solids cannot conduct electricity in the solid phase. They only do so in the liquid phase. While they are solid, the ions in the ionic solid are fixed in their lattice so cannot move to conduct electricity whereas in the liquid phase, the ions are free and mobile and can act as charge carriers for electricity.
Do covalent compounds conduct electricity as liquid or solid?
covalent compounds don't conduct electricity in any state.
Can water conduct electricity in solid state?
No. Water can only conduct electricity in its liquid state with dissolved ionic solutes.
What metals can't conduct electricity?
By definition, a solid metal, including liquid mercury, in its elemental form should conduct electricity. Under what condition a metal cannot conduct electricity? Normally when a metal is oxidized, the result is highly resistive, but then the oxide film (such as rust) is no longer considered metallic. Some metals, such as sodium, don't normally exist in its elemental form in nature. If these metals are somehow kept out of trouble (air), they too should conduct electricity. ==================================
Can a nonpolar molecule conduct electricity in either its solid or liquid state?
No.
Is network solid a poor conductor of electricity?
network solids do not conduct electricity in the solid or liquid phase, but yes in the aqueous phase
Does copper sulfate conduct electricity?
Copper sulphate can conduct electricity. However, this will only happen when it is in liquid or gaseous state but not in solid form.
