Because they are not dense enough and do not have enough free electrons to pass electricity efficiently. Although electricity can pass through non-metals if enough energy is present, for example lightning travels through many miles of air before it hits the ground.

∙ 16y agoThe answer is that some non-metals can conduct electricity.Carbon for example can conduct electricity. The real question is what is the difference between conductors and insulators. In order for electric to flow the electrons in the other ring of the atom must be able to easily remove themselves from this ring and allow electricity to flow. Most metals are in this situation as well as other atoms. Insulators don't easily give up these electrons and are insulators. Plastic, rubber and wood are some examples.

∙ 13y agoNonmetals are poor conductors based on there elements and reactions. For example Noble gases on the Periodic Table are nonmetals they inert gases based on there reactions. They cannot transfer heat and electric currents well.

∙ 14y agoMetals have de-localized electrons - electron clouds that do not "belong" to any one atom. When you try to feed electrons in one end of a metal rod, if the rod has a place on the other end where electrons can go then it is more happy to let electrons pour in one side of the rod and out the other. The more loosely the cloud is held, the less the resistance and the better the conductor.
In contrast, no-conductors have electrons in fixed orbitals. In order to shove electrons from one side of the rod to the other you need them to shove fixed electrons out of their places - a task that requires a large amount of energy, and therefore a large resistance.
However, in 2004, a breakthrough was made...(follow the link)

∙ 12y agoThey cannot because they have no Free mobile electron. We all know that in solid electrons are carrier of electricity while ions are carrier in liquids.but note that some non-metal can conduct electricity like graphite an allotrope of carbon.
Firstly, there are non metals that can conduct electricity (ionic compounds), except they have to be dissolved to do that. One example is the salt used for cooking (NaCl in chemical formula). When dissolved, the ions are able to move freely and conduct electricity. Otherwise, like other non-metals, the particles are held in the structure and able to move freely, resulting in non-metals being unable to conduct electricity. Although metals are also held in a structure, they have free moving ions that can conduct electricity throughout the metal, allowing it to conduct electricity.

∙ 9y agoNon metals simply just cannot conduct heat very well. This is because they are not naturally and anatomically designed to be able to do so.
Wiki User
∙ 13y agoDue to unavailability of free electrons, non-metals have low electrical conductivity and a high resistivity.
Wiki User
∙ 13y agoIn the case of non-metals their energy gap is >5ev. So a large amount of energy is needed for conduction.

∙ 12y agothis is because non metal have no free mobile electron that carry charges round it

Is astatine a good conductor of electricity?
Astatine is not a good conductor of electricity. This is because it is a non-metal. All non-metals do not conduct electricity, and all metals do. The two exceptions are carbon and silicon, which are non-metals, but conduct electricity well.
How do metals differ from nonmetals?
Metals usually have characteristic(s) of at least one of the following: luster, shine, malleable, ductile, and conducts electricity. Non metals don't conduct electricity and are usually brittle.
How do you differentiate metals from non metals?
Metals usually have a characteristic lustre, so you can often tell just by looking. The metals conduct electricity when solid, and non-metals, with the exception of graphite, do not. Metals react with oxygen to give basic oxides, whereas non-metals give acidic oxides.
Is a metal or non metal a nonconductor?
Almost everything is a good conductor of sound, but a conductor of heat and electricity are usually only metals. A nonmetal can be an insulator, or something that doesn't conduct things, for heat and electricity.
Do the transition elements display metallic or non metallic properties?
The transition elements are metals. As with all metals, the transition elements are both ductile and malleable, and conduct electricity and heat.
Which can conduct electricity metals or non-metals?
Mainly metals. All metals are fairly good conductors. Some non-metals can conduct electricity, as well.
What are the physical properties of metals non metals and noble gases?
metals conduct heat, transmit electricity, and are usually ductile. non-metals do not conduct heat well, do not transmit electricity and can't be hammered into shapes. noble gases cannot combine with any other elements.
What do metals do more easier then non metals?
conduct electricity
Which metals do not conduct electricity?
all metals conduct electricity but alumiun doesn't conduct it as well as others all metals conduct electricity but alumiun doesn't conduct it as well as others
Are there no non-metals that conduct electricity well?
Graphite is a non metals which conducts electricity well.Also there are electric conducting non metal.Also many liquids conduct electricity.Semi conductors like Silicon,Germanium also conduct electricity.
Is astatine a good conductor of electricity?
Astatine is not a good conductor of electricity. This is because it is a non-metal. All non-metals do not conduct electricity, and all metals do. The two exceptions are carbon and silicon, which are non-metals, but conduct electricity well.
What is one characteristic of a nonmetal?
Metals conduct electricity; non-metals do not.
Do non metals conduct electricity and are often shiny solids?
no
Why are non reactive metals used for jewelry?
Because they do not conduct electricity <><><> Sorry- above answer is DANGEROUSLY incorrect- ALL metals conduct electricity- gold and silver especially. However, non-reactive metals do not tarnish or rust- they stay pretty.
What are some properties that metals have that non metal don't have?
Metals are malleable (can be shaped and formed), conductable (electricity), and have high melting points. Nonmetals are brittle, cannot conduct electricity, and have very low melting points.
Is limestone a insulator?
Metals are very good electricity conductors. Metalloids are half metals, half non- metals which can conduct electricity, but not as good as metals can. Limestone is a sedimentary rock composed largely of the minerals calcite and/or aragonite, which are different crystal forms of calcium carbonate (CaCO3). Therefore, limestone cannot conduct electricity. TheLostJammer
What is the group of elements called that do not conduct electricity?
The group of elements that do not conduct electricity are generally called non metals.
