Metals, such as copper and silver, allow electrons to move freely and carry with them electrical charge. ... We now think of this state of matter as neither a metal nor an insulator, but an exotic third category, called a superconductor.

What metals can become superconductor?

But at very low temperature, some metals acquire zero electrical resistance and zero magnetic induction, the property known as superconductivity. Some of the important superconducting elements are- Aluminium, Zinc, Cadmium, Mercury, and Lead.

Can metals be superconductors?

Background. Type 1 superconductors are mainly metals and metalloids that show some conductivity at room temperature. They were the first materials found to exhibit superconductivity. Mercury was the first element observed to display superconducting properties in 1911.
