Do swarvorski crystals conduct electricity?

You mean 'Swarovski' and technically (if it's clear), it's just cut glass and would have said conductance properties. If it's colored, they probably used some additive, maybe lead, so it might be moreso.

The handle contains a power cell. Adegan crystals focus the energy of the power cell into the beam.

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.

If u meant what solution would conduct electricity then any salt solution would do  the trick. If you meant what solution would produce electricity to light a bulb then you need to prepare a dilute solution of sulphuric acid ( be careful! wear gloves! Wear goggles! If you are a kid, do it under supervision of an adult..that means your parents or teacher :-) ) In the acid solution suspend two plates of dis-similar metals ( say zinc and copper) and connect the plates to the bulb( a flash light bulb, 1.5 V) using copper wires..and see it glow.\n\nThere are other ways and more elegant styles..however this is the simplest.

The structure of graphite is planer. There are planes of carbon atoms well bonded together. Between these planes there are more electrons (I think) - but they are free to move. \n\nWhen you apply a voltage, these electons do move - and moving electons is current - ie it conducts

The conduction band is not really related to the energy levels of electrons in an atom. Instead, it is about how electrons behave in a crystal lattice.\n\nIf you think about it, when you try to get an electron to move through a solid, it is going to keep coming across nuclei that will stop it in its tracks or bounce it back. So how on earth does anything conduct?\n\nThe answer is that electrons behave like waves. So the crystal lattice behaves like a 3D diffraction grating. You will have seen 1D diffraction gratings  splitting light into a spectrum. What this tells you is that photon of a given energy can go easily in one direction but not at all in another (the dark bands). The same applies - but more complicated - to the electrons in a crystal (metals are crystalline in structure).\n\nYou can think of it this way - in some directions the electron can wiggle around all the nuclei because the spacing is a multiple of its wavelength, in others it cannot.\n\nBecause electrons are no free to move as they please in a metal then the usual rule that their energy will vary with the square of their momentum does not apply. The band structure of a material shows how energy and momentum are related. It varies in different directions in the material.\n\nImportantly, the band structure has a gap in it. This gap is the area where there is no momentum an electron can have to have a given energy (you can see why this exists above). The band below this gap is called the valence band. The band above is called the conduction band.\n\nBecause of the Pauli exclusion principle. no two electrons can have the same state (i.e. the same momentum/energy/spin relation). So the bands fill up from the bottom.\n\nTo conduct, it must be possible to add some momentum to an electron to make it move. You can see that if the valence band is full, then you have to give a lot of energy before you can change the momentum because there is a gap before you find a vacant state. \n\nMaterials with a full valence band and empty conduction band are insulators.\n\nMaterials with some electrons in their conduction band are conductors.

The following is from Wikipedia:\n\n"In a normal conductor, an electrical current may be visualized as a fluid of electrons moving across a heavy ionic lattice. The electrons are constantly colliding with the ions in the lattice, and during each collision some of the energy carried by the current is absorbed by the lattice and converted into heat (which is essentially the vibrational kinetic energy of the lattice ions.) As a result, the energy carried by the current is constantly being dissipated. This is the phenomenon of electrical resistance."\n(See "superconductor")\n\nAs to length and disregarding superconductors, any unit length n of a material has the property of electrical resistance.  Since resistances in series add, a length 2n will have 2 times the resistance of a length n, etc.  Also see "resistance" in wikipedia, where rho is defined.

By "natural magnet", I assume you mean the mineral magnetite (Fe3O4).  At room temperature (and at temperatures below ~850 K) magnetite is a semiconductor, above ~850 K, it is behaves like a metallic conductor.\n\nThe resistivity of pure magnetite at room temperature is about 0.33 ohm*meter, which is close to that of pure germanium (=0.46 ohm*meter).  "Good" conductors of electricity (like metals) have resistivities less than about 10^-6 ohm*meter, while good insulators have resistivities greater than aabout 10^9 ohm*meter.  As you can see, at room temperature, magnetite lies somewhere in between.

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

Insulators do not have free electrons to conduct heat or electricity.\n\nMetals, on the other hand, DO have free electrons, and so conduct electricity and heat.  ALL elements can be classified as either conductors, semiconductors, or insulators, depending on how easily electrons will flow.\n\nThe only exception to this rule is diamond, which is an electrical insulator (no free electrons), but an excellent heat conductor.  (The reason is that heat can be transferred by atomic vibration of the diamond crystal lattice, but electricity cannot)

There are different types.\n\nHowever, the gold leaf electroscopes have two very thin leaves (not necessarily made of gold) attached to a conductive rod. The rod has a metal knob at the other end.\n\nWhen some charge is imparted to the knob, the charge flows to the leaves. As the two leaves same type of charge (either positive or negative), they repel each other.\n\nAmount of charge can be estimated by the amount of separation of the leaves.

If the conductance band is very narrow, it results in a very high effective mass for the carrier.  This is because: giving velocity to the carrier increases its total energy.  If this total energy isn't within the band then the carrier can't be given it and so moves slowly.\n\nYour case would seem to be an N type good conductor,possibly a metal.

Yes, it IS possible that positive charges can flow in a conductor. Consider a solution of NaCl in water - this solution conducts electricity in the form of Cl- AND Na+ ions moving in opposite directions. In plasma, current is carried by both the free electrons and protons flying around. Electrical current is far more general than just the elementary-school simplification of electrons moving through a wire.

A crystalline lattice through which electrons flow freely would be a superconductor.  So far, we don't know of any material (elemental or not) that is a superconductor at room temperature; however, several elements have been found to have superconducting crystalline lattices at very cold temperatures.  There are four known elemental Type 2 superconductors:  Carbon, Vanadium, Technetium and Niobium.  Carbon has the highest temperature at which it becomes a superconductor; however, since you specifically asked about crystalline lattice, it should be pointed out that Carbon only does this as a Fullerene nanotube, not a traditional crystal.\n\nHere are lists of the four type 2 and all of the type 1 superconducting elements, and the temperatures and crystalling structures with which they superconduct.\nhttp://superconductors.org/type2.htm#niobium\nhttp://superconductors.org/TYPe1.htm#cooper

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.....
