Metals are excellent conductors of electricity and heat because their atoms form a matrix through which outside electrons can easily move. Instead of orbiting their individual atoms, they generate a sea of electrons around the positive nuclei of the interacting metal ions.
To some extent, most metals carry electricity. Some metals carry electricity better than others.
Its atoms are intimately linked, and glass is employed as an insulator.
Silver is the most efficient conductor of all known materials. On the other hand, is not often used for its conductive properties due to its high cost and limited availability.
Copper is less conductive than silver, but it is less expensive, and it is used as an effective conductor in many household pieces of equipment.
