ch3cooh is Ethel alcohol.\n\nNa cl is salt.\n\nSalt is the better conductor, and the higher concentration of .2 moles is the better conductor.\n\nWilliam

Pure silver is nearly white, lustrous, soft, very ductile, malleable, it is an excellent conductor of heat and electricity. It is not a chemically active metal, but it is attacked by nitric acid (forming the nitrate) and by hot concentrated sulfuric acid. It has the highest electrical conductivity of all metals, but its greater cost has prevented it from being widely used for electrical purposes.\n\nSilver is almost always monovalent in its compounds, but an oxide, a fluoride, and a sulfide of divalent silver are known. It does not oxidize in air but reacts with the hydrogen sulfide present in the air, forming silver sulfide (tarnish). This is why silver objects need regular cleaning. Silver is stable in water.\n\nProperties\n----------\nAtomic number 47\nAtomic mass 107.87 g.mol -1\nElectronegativity according to Pauling 1.9\nMelting point 962 °C\nBoiling point 2212 °C\nVanderwaals radius 0.144 nm\nIonic radius 0.126 nm\nIsotopes 11\nElectronic shell [ Kr ] 4d10 5s1\nEnergy of first ionization 758 kJ.mol -1\nEnergy of second ionization 2061 kJ.mol -1\nDiscovered by The ancients\n\nDensity of solid [/kg m-3]: 10490  \nMolar volume [/cm3]: 10.27  \nVelocity of sound [/m s-1]: 2600  \n\nElastic properties\nYoungs modulus [/GPa]: 83  \nRigidity modulus [/GPa]: 30  \nBulk modulus [/GPa]: 100  \nPoissons ratio [no units]: 0.37  \n\nHardnesses\nMineral hardness [no units]: 2.5  \nBrinell hardness [/MN m-2]: 24.5  \nVickers hardness [/MN m-2]: 251  \n\nElectrical properties\nElectrical resistivity [/10-8 Ω m; or mΩ cm]: 1.6  \n\nReflectivity [/%]: 97

Mercury has a Rhombohedral crystal structure, which means that it is close packed.  The close packed structure of the mercury will have a greater efficiency in conducting electricity compared metals such as alkaline earth metals which are packed less efficiently having 8-co-ordinated structure.  The reason why it can conduct electricity well is because it is a metal containing atoms with relatively large numbers of free electrons and it is efficiently packed.  With such structure, the electrons flow from one atom to another when electrical field is passed through quite well.  Although it is not considered to be an ideal electrical conductor, Mercury is a fairly good conductor with electrical conductivity of 10.163 1/mohm-cm.

carbon has no free electrons available\nso it cannot conduct electricitys\nin case of germanium and si they have d orbits in the outer shell and they have greater mobility

not electrically conductive. carbon is the only non metal conducting element. and as for that idiot who says yes because they use it in batterys...sulphuric acid...is an ACID... ie donates H+ ions and thus leaves a - charged end behind and ions in solution will allow a current to flow

A dielectric material is one that doesn't conduct electricity and can also be referred to as a conductor. This means they don't have many "free" electrons zooming throughout the material, ie not very many electrons that are tied to one specific atom in your solid. Asbestos and diamond are both examples of conductors.

generally speaking it goes from greatest conductivity = lowest temprature to least conductivity = highest temp.  Heat increases the randomness and thereby slows conductivity.

earth of course......\nthere is a layer in our blue planet called the mantle which lies between the outer crust and the core.. its the biggest layer even...

Francium and cesium are about 0.5.\nFluorine is highest at 3.9-4.0 (by Pauling's estimate)

Simply put, it's not a conductor. \n\nhttp://jchemed.chem.wisc.edu/JCEsoft/CCA/CCA1/MVHTM/R0540/S567.HTM

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)

The chemical element with the highest melting point is carbon, (4300–4700 K) (4027–4427 °C,7280–8000 °F).

Na+ and K+ (both group 1)\nCa2+ and Mg2+ (both group 2).\nNa+ and Mg2+ have the electron arrangement of neon, and the other two that of argon.\nIonic radius decreases from left to right, and increases top to bottom, so K+ is the largest of all these.\nElectronegativity increases upwards and to the right of the Periodic Table, so Mg has the highest value of these four.

Heavy Metal! Just joking. http://www.scienceproject.com/projects/intro/elementary/EX057.asp Go here, they have a lot of information.\n\nhttp://www.science.ca/askascientist/viewquestion.php?qID=1216 And this one. It is clear that aluminum conducts the best heat.

it's silver. it used to be used in telegraph/telephone wires, but when the poles got knocked down by storms, people would pull out miles of the silver wire and sell it to jewelers and pawn shops. that's why they switched to copper: it is the most conductive, non-precious metal.

There are only two types of electric charges that can conduct electricity:  electrons and ions.\n\nVegetable oil has no free electrons.\n\nVegetable oil with some dissolved atmospheric moisture might be slightly conductive because the water can be ionized, but dry vegetable oil has no ions.\n\nTherefore, it is safe to say pure vegetable oil is an insulator and not a conductor (at low voltages, say, below 600 Volts).
