bond", it is preferable to use the term metallic bonding, because this type of bonding is collective in nature and a single "metallic bond" does not exist. Not all metals exhibit metallic bonding: one such example is the mercurous ion (Hg2+2), which forms covalent metal-metal bonds. ...
Unlike its lighter neighbors, cadmium and zinc, mercury usually forms simple stable compounds with metal-metal bonds. 与同组的锌和镉不同的是,汞一般通过金属键形成简单稳定的化合物。 WikiMatrix The existence of the metal-metal bond in Hg(I) compounds was established using X-ray studies in ...
A direct bond between metallic members and non-metallic members is achieved at elevated temperatures in a controlled reactive atmosphere without resorting to the use of electroless plating, vacuum deposition or intermediate metals. A metal member such as copper, for example, is placed in contact with...
