What are some non- metals that conduct electricity ?

Hint: To answer this question, we first need to understand what nonmetals are. A nonmetal is a chemical element that does not have the same properties as metals. A nonmetal has a low melting point, boiling point, and density in terms of physical properties. When solid, a nonmetal is typically brittle, and it has poor thermal and electrical conductivity.

Complete answer:
Electricity:The set of physical phenomena connected with the presence and motion of matter with an electric charge is known as electricity. Electricity and magnetism are both part of the electromagnetic phenomena, as defined by Maxwell's equations. Lightning, static electricity, electric heating, electric discharges, and many more common phenomena are all related to electricity.

An electric field is created by the existence of an electric charge, which can be positive or negative. A magnetic field is created by the movement of electric charges, which is known as an electric current. So, we conclude that, Non-metals are substances that do not conduct electricity. After metals, they are the second-largest elemental group. They don't have any free electrons, unlike metals.

The only non-metal that transmits electricity is carbon. When graphite is included, it is regarded as a semimetal. One valence electron of each carbon atom remains free in a graphite molecule, making graphite an excellent conductor of electricity. They don't have any free mobile electrons in diamond. As a result, there will be no electron flow. The diamond is the result of a lousy conductor of electricity.

So, the final answer is, graphite.

Note: Graphite, sometimes known as plumbago, is a crystalline form of the element carbon with atoms organized in a hexagonal pattern. It is the most stable form of carbon under ordinary conditions and occurs naturally in this form. It turns to diamond at high pressures and temperatures.
