Does Magnesium Conduct Electricity? A Scientific …

Magnesium does conduct electricity. This alkali earth metal’s conductive properties were a key part of its initial isolation. (1) In 1808, British scientist Sir Humphrey Davy built a large battery out of magnesium and was able to pass electricity through salts, predating today’s use of magnesium in cell phones, laptop computers, and hybrid automobiles.

Why does a salt not conduct electricity in its solid …

Salts consist of ions: charged particles. In the solid state however, the ions are trapped in a lattice by electrostatic forces. This means that the charged particles cannot move around freely and therefore salts do not conduct electrivity in their solid state. Answered by Thomas D. • Chemistry tutor. 11349 Views.
