In recent years, physicists have discovered materials that are able to switch their electrical character from a metal to an insulator, and even to a superconductor, which is a material in a ...

An element's location on the table can be used to determine its electron configuration. By following the order of periods (rows) and blocks (s, p, d, f), you can trace how electrons fill the atom's ...

If electron correlations have any effect, such perturbations of electron configurations would meet resistance, since electrons naturally repel each other. For example, an electron that attempts to ...
