name the non-metal which is a good conducter of electricity?

The answer you are probably looking for is graphite, which is an allotrope of carbon. Just "Carbon" isn't a good answer because in the form of diamond or buckyballs carbon is almost completely non-conductive.\n\nSimilarly water isn't a good answer since water is a pretty good insulator. Only by dissolving metals such as sodium in the water can you make it conductive.\n\nHaving said that there are any number of other non-metallic conductors, but graphite carbon is probably the answer the teacher wants.

An insulator is a material containing no electrical charges. When a voltage is sent across an insulator, no charges flow, so there is no electrical voltage\n\nGenerally,all non metals materials are good insulators.Such as plastic,glass,rubber(frying pot handle)

A conductor is defined as a material with high conductivity, although this judgement is somewhat subjective.  Metals are good conductors because metals are, by definition, held together by metallic bonds, in which electrons are free to move throughout the structure.  Thus, metals are always good conductors compared to non-metals.  Some metals are much better conductors than others.

electricity (î-lèk-trîs´e-tê), class of phenomena arising from the existence of CHARGE. According to modern theory, most ELEMENTARY PARTICLES of matter possess charge, either positive or negative. Two particles of like charge, both positive or both negative, repel each other; two particles of unlike charge are attracted. The electric FORCE between two charged particles is much greater than the gravitational force between the particles. Many of the bulk properties of matter are ultimately due to the electric forces among the particles of which the substance is composed. Materials differ in their ability to allow charge toflow through them. Those that allow charge to pass easily are conductors,  whereas those that allow extremely little charge to pass through are called insulators,  or DIELECTRICS. A third class of materials, called SEMICONDUCTORS, is intermediate. Electrostatics is the study of charges, or charged bodies, at rest. When positive or negative charge builds up in fixed positions on objects, certain phenomena can be observed that are collectively referred to as static electricity. The charge can be built by rubbing certain objects together, such as silk and glass or rubber and fur; the friction between these objects causes ELECTRONS to transfer from one to another with the result that the object losing electrons acquires a positive charge and the object gaining electrons acquires a negative charge. Electrodynamics is the study of charges in motion. A flow of electric charge constitutes an electric current. In order for a current to exist in a conductor, there must be an ELECTROMOTIVE FORCE (emf), or POTENTIAL difference, between the conductor's ends. An electric CELL, a PHOTOVOLTAIC CELL, and a GENERATOR are all sources of emf. An emf source with an external conductor connected from one of the source's two terminals to the other constitutes an ELECTRIC CIRCUIT. Direct current (DC) is a flow of current in one direction at a constant rate. Alternating current (AC) is a current flow that increases in magnitude from zero to a maximum, decreases back to zero, increases to a maximum in the opposite direction, decreases to zero, and then repeats this process periodically. The number of repetitions of the cycle occurring each second is defined as the frequency, which is expressed in HERTZ (Hz). The frequency of ordinary household current in the U.S. is 60 cycles per sec (60 Hz), and electric devices must be designed to operate at this frequency. In a solid, the current consists not of a few electrons moving rapidly but of many electrons moving slowly; although this drift of electrons is slow, the impulse that causes it moves through the circuit, when the circuit is completed, at nearly the speed oflight. The movement of electrons in a current is not steady; each electron moves in a series of stops and starts. In a direct current, the electrons are spread evenly through the conductor; in an alternating current, the electrons tend to congregate along the conductor surface. In liquids, gases, and semiconductors, current carriers may be positively or negatively charged.

Actually the answer to this question is slightly more complicated than the average cynic would have it.  (By the way, sodium is a metal).\n\nMetals have several properties common to them:\n1.  They conduct electricity\n2.  They are ductile, and malleable\n3.  They are GENERALLY white and lustrous (few exceptions, such as copper, gold...lustrous but yellow/red)\n4.  They conduct electricity and heat very well.\n5.  They have generally low electronegativities compared to non-metals.\n\nFor non-metals, reverse these properties and you have a good physical description.  E.g.  They don't conduct electricity or heat very well, they're not malleable or ductile, they're generally not lustrous, their electronegativities are relatively high, etc.  \n\nYou find most metals GENERALLY to the left on the Periodic Table, while you find non-metals generally to the right.  That notable jagged line you see on many periodic table examples is said to divide the two categories, but it's a fuzzy line at best.  There are metalloids, for example, that contain SOME properties of each, making life interesting for us chemists who like to classify things.

Typically the metals and hydrogen. Non-metals usually give negative ions.

copper and aluminum are best electricity conductors. I would say lead, since it's one of the densiest material out there. Heat is caused by vibrating atoms, denser material means the atoms are closer, and it's melting point is low too. As soon as you touch it with a hot soldering iron, the heat transfers right away and melts it.

A metal (Greek: Metallon) is an element that readily forms positive ions (cations) and has metallic bonds. Metals are sometimes described as a lattice of positive ions surrounded by a cloud of delocalized electrons. The metals are one of the three groups of elements as distinguished by their ionisation and bonding properties, along with the metalloids and nonmetals. On the periodic table, a diagonal line drawn from boron (B) to polonium (Po) separates the metals from the nonmetals. Elements on this line are metalloids, sometimes called semi-metals; elements to the lower left are metals; elements to the upper right are nonmetals.\n\nA modern definition of metals is that they have overlapping conduction bands and valence bands in their electronic structure. This definition opens up the category for metallic polymers and other organic metals, which have been made by researchers and employed in high-tech devices. These synthetic materials often have the characteristic silvery-grey reflectiveness of elemental metals.\n\nThe 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.\n\nRest all are non metals.

No it isn't!\n\nWhy? Lightning! One of the easiest ways for lightning to travel into your home is through your water pipes, and it will travel right to your body since water has a high conductance. Things to stay away from include phones and computers, since lightning may also travel through the lines that are outside of the house.\n\nRemember, lightning doesn't need a metal object to travel into your home, anything that is a conductor will do.

actually none of those make good insulators, they are all a type of metal or combination there of. if anything they are all conductors, not insulators. if you need a good insulator glass, or porcelain, for PVC and i guess it also depends on what you are trying to insulate but those choices are not good for insulating anything.

copper can't produce electricity. it conducts electricity

research is currently being carried out on this area. materials which work better at room temperature and have similar properties to a semi conductor are already being developed. giveit another 25-30 years we may have some. who knows.....

No, copper is NOT cheap, it costs quite a bit more than aluminum pound for pound. Copper has a much lower resistance to electricity than aluminum does. When subjected to the loads household wiring have to deal with, aluminum wiring would have to be prohibitively thick to prevent overheating. Copper provides the best conductivity with the best compactness for the best price.

yes, it is made of iron or steel, which is good electric conductor

it can only pass through non-conducting material. If you used "pure" water it would pass through. pure water is non-conductive. It is the dissolved minerals and metals in the water that makes it conductive.
