摘　　要：对于重金属相对论效应不可忽视。由于金的相对论效应显著大于其他元素,因此原子半径收缩大,惰性电子对效应也大,加之金特有的电子构型,使金具有独特的化学性质,即金不仅可氧化为正一价和正三价,还可以呈负一价。Relativistic ettect is not to be neglected m heavy metals. 19ue to me OOVlOUSiy greater reiauwsuc elicit than other metals, gold has wide range of atomic radius and great effect of inert electron pair. Adding that gold has u- nique electronic configuration, special chemical property of gold emerges ,that is, gold ions can not only take the form of valence positive one and three, but also valence negative one.

关 键 词：原子结构 负价金 相对论效应 惰性电子对效应 电子构型
