Although metals and salts have similar lattice structures, metals make good materials for electrical wiring. Why aren’t salts used instead?
Salts do not conduct electricity. Metals do. Electricity runs through the metal.
Metals have electrons which rather leap from atom to atom, offering electric powered present day. Salts regularly have a steel and nonmetal at usual durations. The electrons are tightly shared between the ion pairs and are not loose to shuttle.
