Carbon in the form of graphite is used as an electrical conductor (the brushes in electric motors)
Yes, sodium is a better electrical conductor than francium. This is because sodium has one valence electron that can easily move and carry electrical charge, whereas francium has only one valence electron that is trapped in an inner shell by its atomic structure, making it less available for electrical conduction.
copper is a very shiny metal, with an orange-gold colour. It is a really good conductor of electricity, second only to silver. it doesn't corrode easily and is ralatively cheap since its very abundant. its very malleable and ductile.
Its electrical conductivity is not known. The thermal conductivity is only 5.65×10^−3 W/(m·K). By way of comparison, silver, the best conductor has a conductivity of 430 W/(m·K) - more than 75 thousand times as great.
Neodymium does conduct electricity. It's conductivity, however is about 1/50th that of copper, which makes it a fairly poor conductor as far as metals are concerned. Not all magnetic substances conduct, however. Ferrite for example is an iron ceramic compound which allows it to be magnetized, even as an insulator.
Mercury is the only metal that is liquid at room temperature. It is used in thermometers, barometers, and some electrical switches and relays.
water
it is a conductor but its electrical conductivity is only 28%as conducive as copper.
That would be water.
Graphite
diamond
Because electricity can only travel through metal.
yes copper is a good conductor of heat only becuase it comes in the conductor of heat
Graphite is a non-metal conductor due to its structure that allows electrons to move freely between its layers.
Note: "electricity" is not conducted, only electrical current (the flow of electrons) is. Electricity is the field that covers all things electrical. The wood in a pencil is an insulator. If it is wet, it is a poorer insulator, but only a poor conductor. The carbon (lead) in the pencil is a poor conductor. The metal holding the eraser is a good conductor. The rubber eraser is a poor conductor. You really have to address the conductivity of specific substances, not items that are build from a variety of substances.
Metal is a good conductor. Any charge will quickly be distributed over the entire metal piece.
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.
For most applications ... where the wire has no function other than to join the components that accomplish the purpose of the circuit ... the best metal to use for wiring would be the one with the smallest resistivity. That would be silver. A big part of the reason that we usually settle for copper is because it is only second best as a conductor and is a lot less expensive than silver.
