How many gold atoms make gold metal?
Departments of Physics and Chemistry, Nanoscience Center – University of Jyväskylä , FI-40014 Jyväskylä, Finland
It is well known that a piece of gold is an excellent metal: it conducts heat and electricity, it is malleable to work out for jewellery or thin coatings, and it has the characteristic golden colour.
