The conductivity of solids depends on the number of free electrons they have and how much they can move around freely before bumping into something and stopping. Metals are generally good conductors because they have a lot of free electrons that can wander around carrying energy. Other solids have few or no free electrons so they are not good conductors.

∙ 15y agoAll solids are not good conductors of electricity my friend. Only Metals,Semiconductors and Salts (in fused state) are. 1.In metals the good electric conductivity is due to the abundance of electrons in their conduction band. 2.Salts in their fused state(melted in a solvent such as water) get dispersed into oppositely charged ions. 3.In semiconductors electrons are present in between conduction and valence band.

∙ 14y agoSolids are not necessarily better conductors than liquids; it depends on your solid and on your liquid. The elements can be divided into three categories metal, metalloid and non-metals. Metals are great conductors of electricity, non metals are poor and metalloids are in between and called semi-conductors. Pure water is a poor conductor of electricity, however, if you add electrolytes (like in your favorite sports drinks) than it becomes a good conductor. An electrolyte is a salt (the secret ingredient in sports drinks — salt) added to a liquid, which then makes the liquid conduct electricity. Salt in water breaks up into ions which carry the charge through the liquid. To answer your question, the property which makes something a good conductor of electricity is its ability to lose electrons. Metals have a very weak hold on their valence electrons (electrons in the outer most shell). This is what gives metals their various metallic characteristics, such as conductivity, being able to be stretched into a wire (ductility) or hammered flat ( malleability). The loose electrons can easily pass from one to the other carrying the charge (and heat) with it along the way.

What physical properties do metals have?
1-they are good conductors of heat & electricity 2 they have luster 3-they are ductile 4-all of them in the form of solids
Does magnesium conduct heat and electricity?
Yes. Magnesium is a metal and all metals are great conductors of heat and electricity. Nonmetals are not good conductors and metalloids are in between.
What element is and good conductor of heat and electricity?
Almost all metals are good conductors of heat and electricity but alkali metals such as silver are very good conductor of heat and electricity.
Is insulation a property of metal?
No. metals are good conductors of both heat and electricity. Insulation is a property of non metals.
What are metallic minerals good conductors of?
Some of the electrons in metals have energy levels putting them in the "conduction band", meaning they're shared kind of throughout the bulk of the entire metal instead of being localized into a single atom or molecule.
What is true about most metals?
Metals are good conductors of heat and electricity. They have a metallic luster. All the metals are solids except Mercury.
What solids are good conductors?
All metals are solids and good conductors apart from Mercury which is a liquid but is a good conductor.
What are the characteristic metals?
They are good conductors of heat and electricity. They have a metallic luster. All are solids except mercury.
What physical properties do metals have?
1-they are good conductors of heat & electricity 2 they have luster 3-they are ductile 4-all of them in the form of solids
What are some conductors for heat?
All metals are good conductors of heat.
What makes something a good conductor of heat?
Good heat conductors are drinking glass.
Are all insulators and conductors solids?
No, most gases are good insulators. Fluids can be good conductors. Mercury is normally a liquid and is a good conductor.
Is silver a good conductor of sound?
yea all solids are good conductors of sound
What are some good conductors and bad ones?
Good Electrical conductors: All metals, ionic substances (in solution or molten form) Bad Electrical conductors: Water Good Heat conductors: All Metals Bad Heat Conductors: Water
Are all metals conductors of heat?
We normally associate metals with solids (at room temperature) -- mercury being one exception. All materials, solids or fluids, can conduct heat. However, not all solids are good conductors, but most metals are. I don't know about sodium, a metal, though, because it disintegrates in room air -- not practical to do a controlled experiment to prove about it being a good heat conductor or not. However, since those solids that are classified as a metal for the reason that each metal has free roaming electrons, which can be transport heat, and since solids also have phonons (lattice vibrations), sodium can conduct heat too (at least for the first mini-seconds of being exposed to air) -- just don't know whether sodium is a good heat conductor if it stands alone. BTW, mercury is a good heat conductor too. ===========================
Which metal is a good conductor of heat?
All metals are good conductors of heat.
What metals have thermal conductivity?
ALL metals are pretty good conductors of heat. Some, like gold, are very good conductors of heat.
