Question

why gold doesnt have superconductivity

Answer 1

Im not sure but i think gold is least reactive metal probably thats why

Answer 2

In normal conductors, resistance falls as the thermometer drops, but it never disappears. Superconductors work differently

As a superconductor cools, it follows a similar curve of gradually dropping resistance until it reaches its particular critical temperature; then, abruptly, all resistance disappears.

Actually, the substance undergoes a phase transition. Like ice melting into water, the conventional material is in a new state, one with zero resistance.

When the atoms in a conductor give up electrons, they become positively charged ions, causing a net attraction between the atomic lattice and the negatively charged electrons passing through it.

As the first electron passes through the positively charged lattice, it attracts the surrounding atoms toward it. By bunching up, these atoms create a local area of higher positive charge, which increases the force pulling the second electron forward. This is why only superconductive materials can have zero resistance, because the atom actually assists the movement of the charges past itself

It takes a specific atomic structure that works in conjunction with moving electrons at cryogenic temperatures

Gold doesn't have the right structure to allow those bunched up charges to pass an atom without resistance.
