Atom Wires

Physicists have built the world’s thinnest gold necklaces, at just one atom wide.  The smallest wire width in mass produced electronic devices is about 50 nm, or about 500 atoms across. The ultimate limit of thinness would be wires only one atom wide. Such wires can be made now, although not for any working electronic device, and it is useful to know their properties for future reference.
