Firstly, there are non metals that can conduct electricity (ionic compounds), except they have to be dissolved to do that. most of the non metals do not conduct electricity but there are some exceptions like graphite, Silicon-semi-conductor and metalloids(also semiconductors). Then, why do non metals do not conduct electricity?
Electricity can only be conducted by the motion of electrons or ions. Non-metals do not conduct electricity because unlike metals, they have no free electrons.
Likewise, do all metals conduct electricity? All metals conduct electricity to a certain extent, but certain metals are more highly conductive. The most highly conductive metals are silver, copper, and gold. Copper, for example, is highly conductive and commonly used in metal wiring. Pure silver is the most conductive of all metals.
Hereof, do non metals conduct heat?
A nonmetal is a chemical element that generally does not conduct heat or electricity very well, is usually a solid or a gas at normal temperatures, and (for solids) is difficult to reshape by pounding or beating. Nonmetals include elements such as carbon, sulfur, oxygen, and nitrogen.
Are non metals conductors or insulators?
Metals such as copper typify conductors, while most non-metallic solids are said to be good insulators, having extremely high resistance to the flow of charge through them. "Conductor" implies that the outer electrons of the atoms are loosely bound and free to move through the material.

Non-metals are not able to conduct electricity or heat very well. As opposed to metals, non-metallic elements are very brittle, and cannot be rolled into wires or pounded into sheets. The non-metals exist in two of the three states of matter at room temperature: gases (such as oxygen) and solids (such as carbon). Is shiny a metal or nonmetal?
The periodic table on the left separates elements into three groups: the metals (green in the table), nonmetals (orange), and metalloids (blue). Most elements are metals. They are usually shiny, very dense, and only melt at high temperatures. Their shape can be easily changed into thin wires or sheets without breaking. Is oxygen a conductor of electricity?
Yes, oxygen (or air, at least) can conduct electricity. Since metals conduct heat and electricity well, why do they not "conduct" light (let light through)? Why are non metals brittle?
A nonmetal is an element that is generally a poor conductor of heat and electricity. In the solid state, nonmetals are brittle , meaning that they will shatter if struck with a hammer. The solids are not lustrous. Melting points are generally much lower than those of metals. Can metals conduct heat?
Metals contain free moving delocalized electrons. Metal is a good conduction of heat. Conduction occurs when a substance is heated, particles will gain more energy, and vibrate more. These molecules then bump into nearby particles and transfer some of their energy to them. Does Diamond conduct heat?
Most diamonds are extremely efficient thermal conductors, but electrical insulators. Diamond conducts heat well as a result of the strong covalent bonds between carbon atoms in a diamond crystal. Is bromine a good conductor of electricity?
This structure means that bromine is a very poor conductor of electricity, with a conductivity of around 5 × 10−13 Ω−1 cm−1 just below the melting point, although this is better than the essentially undetectable conductivity of chlorine. Is metal a good conductor of heat?

The traditional definition focuses on the bulk properties of metals. They tend to be lustrous, ductile, malleable, and good conductors of electricity, while nonmetals are generally brittle (for solid nonmetals), lack lustre, and are insulators. Which non metal is lustrous?
Iodine is a non metal which is lustrous in nature. A non metal which exists in liquid state at room temperature is bromine. Graphite, an allotrope of carbon is the non metal which is the conductor of electricity. Why is metal a better conductor of heat?
Metals are particularly good conductors of heat because their particles are very closely packed so the vibrations are passed on very quickly. They also contain large numbers of free electrons. These drift slowly through the structure, giving metals their strength and other properties. Why are non metals insulators?
In a conductor, electric current can flow freely, in an insulator it cannot. Metals such as copper typify conductors, while most non-metallic solids are said to be good insulators, having extremely high resistance to the flow of charge through them. Most atoms hold on to their electrons tightly and are insulators. Which metal is best conductor of electricity?
Copper
Which metal is best for conducting electricity?
The most highly conductive metals are silver, copper, and gold. Copper, for example, is highly conductive and commonly used in metal wiring.
