❓ why
Why do metals conduct electricity better than most nonmetals?
Quick Answer
Metals have delocalized electrons that can move freely through the lattice. Those mobile electrons carry electric current efficiently.
The Full Story
In metals, atoms share a ‘sea’ of electrons rather than holding them tightly to individual atoms. When a voltage is applied, those electrons can move through the crystal structure and carry charge. That is why copper, aluminum, and silver are excellent conductors. By contrast, most nonmetals bind their electrons more tightly, so current cannot flow as easily.
Key Facts
1.Copper is a common electrical conductor
2.Silver is even more conductive than copper
3.Metal bonding includes mobile electrons
