Metallic Radius
Nanometer
A nanometer is a unit of length, having the symbol "nm".
The prefix nano means one billionth, so a nanometer is one billionth of a meter. A meter, the metric base unit for length, is about 3 feet. At such a small distance, individual atoms can be resolved.
Research and engineering that focuses on this nanoscale (typically between 1-100 nm) is called nanotechnology.
