Metals are able to conduct electricity because they have valence electrons. These are electrons that can move through the atoms that make up the metal. As they do so, they are able to pass along electric currents as they... More »

Metals conduct electricity well due to the fact that the outermost electrons in their atoms are held by weak atomic forces, allowing these electrons to flow easily from one atom to another. This flow of electrons is what... More »

The metals that conduct electricity the best are silver, copper and aluminum. Both copper and aluminum are used extensively in electrical wiring. Silver, though it conducts electricity better than either of the other two... More »

Graphite conducts electricity because it possesses delocalized electrons in its structure. The honeycomb layout of the stacked carbon atoms of graphite leaves a single electron unbound in each hexagon. Each of these elec... More »

Although many people think water conducts electricity well, pure water is a poor conductor since its molecules do not have free electrons to travel and thus transfer current. Pure water, however, rarely exists in nature.... More »

Metals are good conductors of electricity, because they have free electrons. These free electrons act as charge carriers in the metallic structure, allowing electric current to flow through the metal. More »

The absence of free electrons in their structures is what generally makes ionic solids poor conductors of electricity. Although ions are electrically conductive when they are unbound, ionic solids exist in crystalline fo... More »
