gold clusters5 d elementsthiol groupbond lengthsquantum chemistryAbstractThe interaction of a terminal thiol group with gold clusters and Au12M intermetallic clusters has been studied by quantum-chemical methods. The energy of addition of the SH group has been found to have the least value for the...
Gold is rare, durable, and – when crafted – considered beautiful. But the reason it maintains such high value is largely abstract and psychological. Also, the metal has across millennia become so intrinsically linked with notions of trade and wealth that the imagined value of gold has become ...
金的物理化学性质(Physical and chemical properties of gold) Physical and chemical properties of gold In the Mendeleev periodic table; the atomic number of gold is 79. That is to say, there are 79 negatively charged rotating electrons around the nucleus of gold. The neighbours in front of the ...

Properties In mass, gold is a yellow-colored metal, although it may be black, ruby, or purple when finely divided. Gold is a good electricity and heatconductor. It's not affected by exposure to air or most reagents. Gold is inert and a good reflector of infrared radiation. It's usually...
Gathered here are those chemical properties which are not covered under the general headings of phase equilibria and crystal structure. The chemical properties of a feldspar can be considered from many viewpoints: thus a crystal chemist emphasizes the chemical bonding, whereas a geochemist emphasizes th...
