You wouldn't want a conductor for a heating coil, conductors aren't supposed to heat. You would want a resistor that would generate heat but still conduct the electricity needed. Nichrome Wire is generally considered the best and most common heating element.

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.

Solid in room temp, but melts in your hand (slightly above room temp)\n\nAlloys quickly with most metals.\n\nYou can read more at the following:

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.

Metals, Nonmetals, & Metalloids\n\nMost periodic tables contain a stairstep line which allows you to identify which elements are metals, nonmetals, and metalloids. Following are descriptions of each of the three types of materials.\n\nMetals\n\nMost elements are metals. 88 elements to the left of the stairstep line are metals or metal like elements.\n\nPhysical Properties of Metals:\n\nLuster (shininess) \nGood conductors of heat and electricity \nHigh density (heavy for their size) \nHigh melting point \nDuctile (most metals can be drawn out into thin wires) \nMalleable (most metals can be hammered into thin sheets) \nChemical Properties of Metals:\n\nEasily lose electrons \nCorrode easily. Corrosion is a gradual wearing away. (Example: silver tarnishing and iron rusting) \nNonmetals\n\nNonmetals are found to the right of the stairstep line. Their characteristics are opposite those of metals.\n\nPhysical Properties of Nonmetals:\n\nNo luster (dull appearance) \nPoor conductor of heat and electricity \nBrittle (breaks easily) \nNot ductile \nNot malleable \nLow density \nLow melting point \nChemical Properties of Nonmetals:\n\nTend to gain electrons \nSince metals tend to lose electrons and nonmetals tend to gain electrons, metals and nonmetals like to form compounds with each other. These compounds are called ionic compounds. When two or more nonmetals bond with each other, they form a covalent compound.\n\nMetalloids\n\nElements on both sides of the zigzag line have properties of both metals and nonmetals. These elements are called metalloids.\n\nPhysical Properties of Metalloids:\n\nSolids \nCan be shiny or dull \nDuctile \nMalleable \nConduct heat and electricity better than nonmetals but not as well as metals

When you say "conductors" are you talking about electrical conductors or thermal conductors?\n\nIf you are talking about electrical conductors, every conductive material has resistance.  Resistance causes the voltage to drop when current passes through.  The product of the two (voltage * current = wattage) is dissipated as heat.  \n\nAmount of heat rise is often the reason for the maximum allowable current for the wire.  (the other is the voltage drop itself)

Copper is used as a conductor and as a easily maliable (formable) metal.  It is also naturally anti-bacterial.

Superconductors are electrical conductors which have a very low resistance.  In the past these materials need to be at very low temperatures.  Recent advances have allowed the creation of HTS (high temperature superconductors) which can operate at very much higher tempteratures than before.

I remember this question since it was on the test once:\n\nList the following kinds of matter by how well they conduct heat (from the best to the worst): Wood; air; metal; water.\n\nMy answer was the correct one and it was: Metal; water; wood; air.

For common metals, iron is pretty much all you have.  Magnetite is an oxide of iron that is the about the most magnetic metal on earth.\n If you are looking for low weight, rare earth magnets are the way to go, but will cost you accordingly.  Neodymium or Samarium-Cobalt are your best bets there.

New research is unlocking the amazing potential of high-temperature superconductors.  The special "talent" of superconductors is that they have zero resistance to electric current. Absolutely none. In theory, a loop of HTS wire could carry a circling current forever without even needing a power source to keep it going.\n\nIn normal conductors, such as copper wire, the atoms of the wire impede the free flow of electrons, sapping the current's energy and squandering it as heat.\n\nToday, about 6 to 7% of the electricity generated in the United States gets lost along the way to consumers, partly due to the resistance of transmission lines, according to U.S. Energy Information Agency documents. Replacing these lines with superconducting wire would boost utilities' efficiencies, and would go a long way toward curbing the nation's greenhouse gas emissions. \n\nThese links provide a wealth of information.  I hope they are helpful to you.

Many of our metals are solid and homogeneous.  Homogeneous does not mean pure (only one thing) -- it only means that the composition is the same throughout the object.\n\nSo gold yes, or silver.  Also many wooden objects, glass, some food items like the center of bread...  The list goes on forever once you start thinking.

To put it most simply, Copper is a metal and sulphur is a nonmetal.  Metals are better conductors of electricity.  If you want to know why metals are better conductors than nonmetals, you should look up band theory.

Metals are to the left of the stair-step line on the table.  They are good conductors of heat and electricity, malleable, ductile, have metallic bonds, and have luster.

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.

The general properties of metals are:\nThey are usually solid (exception is mercury) - argon is a gas\nThey all conduct electricity - argon doesn't conduct electricity\nThey form salts with acids - argon doesn't form any compounds let alone salts.\nThey conduct heat well - argon is a very poor conductor of heat.\nSo argon doesn't qualify as a metal on any count.
