Question

why only some metals are generally used for conducting electricity ?​

Answer 1

Answer:

The main reason why metals are more electrically conductive than other types of material is because its atoms have valence electrons. These are electrons in the outer shell of an atom that can freely move across the lattices of atoms.

Answer 2

Heya !!! Here is your answer:

The electrons in metals allow electricity to move between the atoms. Pure metals tend to provide the best conductivity. The presence of impurities tends to restrict the flow of electrons. This is why alloys are usually poor conductors of electricity.
