Metals (especially copper, aluminum, and [[gold]]) are often very [[malleable]], which means they can be easily shaped into [[wire]]s.

At an [[atom]]ic level, conductors display little opposition to electrical [[current]]; because of this, less [[energy]] is required to generate [[free electron]]s, implying that the number of electrons in their [[Matter#Valence shell|valence shell]] is generally fewer than four (they're [[electron donor]]s). This means that the materials on the left side of the [[periodic table of elements]] are metals, and those extra electrons that make them metals allow for electricity to be transmitted with little loss of [[energy]].<ref>Hyperphysics (July 24, 2015) Electrical Conductivity and Resistivity.

Conductors do experience some degree of resistance ([[conductor resistance]]), albeit a very small amount.
